Today I went to check on our hens (we have 2 hens sharing a box sitting 12 eggs) as today is hatch day. I found one baby on the ground still half way in its shell. I brought it in, warmed it up and assisted it in getting out since it's membrane had dried some and was stuck to the feathers. It's now chirping loudly and happy. I would like to try and introduce it back in. I know there was at least 1 other chick. If it was to reject it, would it be immediately?
