Day 11 and the incubator humidity has been holding between 61-63 % this past week. Definitely see the difference when cloudy weather passes through the area. With the wonderful assistance of Sally we candled a few eggs yesterday evening. I checked one row of 8 eggs and found 7 eggs showing signs of development with dark areas in the yoke and 1 egg with clear fluid. Being my first time visually looking at developed candled eggs I am not comfortable with saying I had 7 lively eggs. However, I candled several of our fresh eggs from the hen house and the visual difference is obvious the 7 candled incubator eggs were different from the fresh eggs and the 1 egg that was clear.
On the eighth day when I checked the water level in the water channel it was mostly evaporated and I added another 4 cups of water. The humidity was still holding at 62% and hadn't begin dropping. This is telling me two things: the eggs themselves probably effects the humidity level and the operator needs to visually check the water channels every 4 days to see what water level one actually has in the incubator.

Buff orpingtons who supplied a few eggs.
Barn yard mix who supplied eggs as well.
This is day 5 into the first round incubation an the eggs look great. The egg turner is rotating the 48 eggs every 2 hours automatically with ease. The humidity has been 57-58 % and this morning it was 52%, later today I will add water to the water channels.

The water channels were refilled and 48 eggs were placed on the egg turner. The count down begins! This photo was taken after sunset and the humidity dropped from the 59% reading throughout the daylight hours today.
A few nice looking eggs! Buff Orpington and mix large brown egg layer hens provided these eggs for the first round incubation. Excited for this 21 day journey!
As day 4 came the humidity level began dropping throughout the day from 59%. The water level had evaporated within the water channels, so the incubator is following the instruction guidelines as it stated you would be refilling the water channels every 4-5 days. I added 4 cups of water to the water channels.
I mentioned earlier the platform tray is tight fitting and you would need something to help lift the tray out from the bottom unit. I made use of a large paper clip and it worked like a charm lifting the tray out.

When my JN8-48 arrived the instructions recommended you set your incubator up and let it run for several days before actually placing your eggs in the incubator. The displays setting are factory pre-set and within the instructions the only adjustment recommended for change is the temperature setting.
The display setting from top left is the egg turner timer (displaying 0147), every two hours the turner rotates and this photo shows 1 hour 47 minutes until the next rotation. The bottom left display is the number of days into incubation (displaying 03 = day 3). The right top display is the temperature setting and the factory setting is 38.0°C and the instructions recommended to lower it to 37.6°C. The green buttons to the left of the temperature are the setting adjustments. Lowering the settings to 37.6°C was easy to adjust by moving the + or - button. The right bottom button is the humidity level reading and the factory alarm setting is 45%, and the present level is 59% and the instructions suggest the humidity level be 60% during the first 18 days. I placed 4 cups of water into the water channels during setup. The instructions stated water would be added every 4-5 days.
When I first plugged-in the incubator and turned the on button on, the alarm bell sounded until the temperature and humidity level reached your desired settings. You can push the setting button to re-set the alarm so you don't have to listen to the beep until the proper settings are reached.
As you can see I am into day 3 of the trial run and the incubator temperature has read 37.6°C and the humidity level read 58% on day 1 and 59% since then.
In 2 days I will place eggs in the incubator.
The JN8-48 parts are made of plastic, the outer shell feels durable for regular handling. Would the plastic crack if you dropped the unit? Probably! The lid has four clear viewing ports and 2 air flow ports. The operation reading display is digital and easy to read and the setting buttons are large enough to push during adjustments or re-set.
Under the hatching tray are two water channels for the humidity during incubation. The hatching tray is tight fitting within the outer shell and if you have large fingers I would suggest finding a tool to hook the tray to lift out from the bottom base. Initial review of the tray looks like it can be cleaned with a brush and a cleaning agent.
The egg turner motor wire plugs into a lead wire on the lid and this restricts the distance you have to move the lid away from the bottom unit during maintenance. The egg turner rotates every 2 hours and the 2013 model is suppose to be made of heavier plastic from the earlier version. Without eggs the turner moves smoothly and I am anxious to see how the tray moves with 48 eggs.
Welcome to Country Life of JANOEL8-48 Incubator. I have been searching for an inexpensive egg incubator these past few months and may I say my search for reviews were lacking the data I wanted to read as to whether a particular model was worth the consideration.
I found a blog thread from Australia that gave several positive reviews towards the JN8-48 newest model and the JN8-48 was in my price range for a beginners use of an egg incubator. If your willing to spend several hundred dollars on an egg incubator, then you'll be able to find good reviews towards the purchase of an upper end egg incubator.
I use sitting hens throughout the summer to hatch my eggs and the success rate is nearly 100%. I have visited with local poultry enthusiast about their success rate with the use of an egg incubator and most have a fair to poor hatch rate with their egg incubator.
I purchased the JN8-48 incubator from E-bay and it arrived last Friday in great condition. I read the instructions and plugged it in for a test period through Wednesday. On Wednesday 48 eggs consisting of Buff Orpington and brown egg layer mix will be placed in the incubator. I will post regular events about the JN8-48 to help the reader get a feel for this particular model.
