I am having an issue with my Farm Innovator 4250 Incubator when it comes to heating evenly. I purchased both incubators separately (one from TSC and one from amazon prime), so it is interesting that the exact same problem is happing with both of them.
I have both incubators set up in my home office, which is at a constant 72-74 degrees and the office door is always closed to eliminate any drafts (I also have baby chicks in my office, so it's a double-down type of situation). I have dark-out curtains on the windows to help reduce any fluctuations in temperature as well due to sun or cold penetration through the window glass. I have additional calibrated equipment to help me maintain the proper environment inside the incubator (100.0-100.5 F, and RH 50-55%) and I thought things were going very well. However...
When I evaluated all the eggs (candle, air sac, weight, etc.), there were many eggs that were noticeably NOT warm from the front rows of both incubators, and a few from the back rows as well. Of course, of the 25 infertile eggs, 10 of them were located in these rows (8 in the front row and 2 in the back row). There were additional "maybe" fertile eggs that I chose to keep on board for Round 2, some in these areas as well. So I wonder if some of these "unfertile eggs" were fertile, but simply did not have the proper environment to really get going.
Does anyone else have this problem with this incubator (or any for that matter), and if so, how have you resolved the uneven temps? It supposedly has a fan, but that doesn't seem to be working all that well. I have now put a thick fluffy towel (1 each) doubled over across the edge and front of the incubator, but that does not seem to be helping as much as I had hoped it would. Do I just not use these 7 slots for eggs? That seems like a waste of space.
Curious to see how other peep-addicts work around this issue!
