So, I neglected the Araucana pen a bit when the Ahole was still in residence so half the hens went broody on staggered eggs... when they started hatching, we found out we had some homicidal broodys... ugh...
I wanted to scrap the eggs and restart, but OH pitched a fit... so he stuck all the 'close to done' eggs in the bottom tray of the Leahy... no water in it, and not really sure what the humidity in it is, but it's pretty dry... for the last week a couple times a day I open it to turn my other eggs and find a chick hatched in that bottom tray... luckily, our really good Am is broody so she has been getting these little buggers as they hatch...
Anyways, Turk, they are pipping, sipping and popping out with absolutely no issues whatsoever... I went with a full out no help, what happens happens attitude and she has a lot of chicks now... not sure exactly how many, but I think around 20...
Take this for what it's worth, but I hope it eases your mind a bit...
