Haha me too. Yolk was completely absorbed.
I have a question- should I put her under the broody now, or tomorrow morning?
Did you say another one already hatched? If so, I'd let this one get up and about a little, but I'd try giving it to her before daylight. If her other eggs have another day or so, then you should probably be able to keep this one inside for another day, if you want. Jmho
Eta it's really up to you, is this momma hen experienced? I know you don't want to lose this chick!
