It's quite close to the fan in that pic too
Are you using the I hatch app? I've downloaded it today, the one from the incubator shop.
I have sticky chicks again. 3hatched good third one had sticky on its butt. 4th one half zipped and stalled . I waited a few hrs. (because I was sleeping) and decided to help. It would of never got out on its own. So far it is the only one that is NOT black. One has been pipped all day. probably stuck too. so thats it 4 babies. Then I went outside and found a baby .
That's not too bad granny
Still only day 20. When you say sticky do you mean shrink wrapped in the shell or they hatch wet with albumen still on them?
