I posted last week that the big girls killed one of our 8 week old chicks (ate the head) after I introduced them. I've read the books, did what I thought was ok, putting a cage next to the coop for 2 weeks, having an area where the chicks can escape, etc. A few mentioned that they thought that maybe a dog got the chickens head and then they pecked her (like the chicken stuck her head out) but now I know that didn't happen. I have 3 hens. After this happened, I fashioned an area in the run for the surviving two chicks to live where the big girls could not get to them at all. (with chicken wire). They are now 9 weeks old. Today I looked out, two of the big girls were in with the chicks and one chick was dead, headless. The other chick had escaped and gone into the coop and was high on a perch. The top of her head is pecked and bloody. I have no idea how the big girls got in there. What do I do now? I have removed the injured chick and put her back in the cage next to the coop. I plan on taking her in every night to the garage. What now??? Can she EVER be introduced with the three big girls? My plan was not to reintruduce them until they were full grown (like 12-14 weeks) and then this happened. She is alone and it scares me to reintro her at any age. I need advice, please help. Should I try to rehome her? I really like her and don't want to but I don't want her dead.
