i checked my hen at around 9:30 pm, she was doing fine with her 2 chicks. Went back out 30 minutes ago, 1 chick was missing. The one chick she has now is being abused by the hen. I'm lost, I honestly thought this was going to work but I guess not I looked everywhere around the coop and could not fine the chick that went missing. What do I do?? What went wrong??
