Hello all, I am a first time poster, first time hatcher- this site is amazing! I recently learned that my neighbor owned and would be happy to lend me an incubator, and decided to try to hatch some experimental mutt chicken eggs. I have light Brahmas, RIR, Black sexlinks, and Americauna girls, plus a light Brahma daddy and a Wyandotte daddy. We got all of our chickens last spring and I am totally hooked. Fast forward- 20 eggs hatched despite an 8 hour power outage early on, and also a temperature spike over night one night... worry worry worry. They were due today but started hatching Sunday afternoon. However, 3 chicks from some of the last eggs to hatch yesterday and last night seem to have ulcers of some sort, I believe from the belly button. I think. Anyway, one seems not too bad, one seems kinda pretty bad, and one poor chic really isn't looking good. What causes this and what can I do if anything??? The other 17 are peeping away, fluffed up, and seem healthy and active. There are still a few eggs that pipped but don't seem to be hatching, and a few that haven't done a thing. I started with 46, pulled 12 that were infertile, and left 34 in the incubator. Is 20 hatched low? Might they still hatch? I'm totally attached to every egg! Sorry- lots of questions I know. Thanks!
