4 that's right, just 4.@PapaChaz so I may have missed it, what was your hatch count?
I attribute it to my fan in the hatcher quitting and me not knowing I needed to bump the temp up to help out.
started with 14 eggs, at day ten one was clear, one was a quitter. at day 18, one more appeared to have quit, but the rest seemed to be good when I put them in the hatcher. Kept the temp 100* and the humidity between 60 -65%. I had tested my hygrometers, so I'd know what I was reading and what to add/subtract. First chick hatched monday, did fine. The other three we discussed through the thread.
today I picked up a computer case fan from the local computer shop for $2, and I have an old wall charger that puts out 12v to wire it to. Tested and it works, I'm trying to decide now what the best mounting position will be. I'll solder and heat shrink the connections, and when I get it in, I'll take pics
