I work at a group home and we have started raising chickens. We have 5 girls who are 1 year old and 5 unsexed chicks around 13 weeks old. 2 of the chicks are Cornish hens. The other caretaker of the chickens (myself and a fellow employee take care of the chickens) tried to introduce the 2 Cornish hens into the flock as they have very much outgrown the enclosure we have the chicks in. He said it went fairly well when he saw on the one of the Cornish hens get pecked on the head. He quickly took the chicks back out and stopped the flow of blood. He also put her in her own separate enclosure. I just went to check on her as I have been off campus all day and was horrified to find a nickel size hole in her skull! I can see her brain The other caretaker had no idea it was this bad as he couldn't see the severity of it due to the blood loss. Bo is eating and drinking and walking and "talking" and doesn't seem to be very affected by the Injury. She let me hold her and she fell asleep on my lap. She is no longer bleeding thanks to the powder. What else can we do besides keep her separated and fed?
