Yesterday I acquired a new bird by chance. I got a call from a friend who'd had chickens in the past before moving to a place where they were under a HOA. She'd spent 45 minutes chasing a chicken in a parking lot before catching her. The bird in question is a RIR hen that appears to be very healthy she drank and ate as soon as we gave her food and water, she doesn't seem skinny, and her combs a bright red. We have her separated in a rabbit cage for now, but I was wondering how long we should keep her quarantined? My other birds are 8 pullets who're about 8 months old and 2 pullets that are about 4 months old. Already have two RIRs one of which is the "boss" so I'm also wondering how integration will go. I think the new one's older than the other pullets- she seemed to be a lot "denser" not necessarily fat but definitely felt heavier than my two RIRs and just seems to be older though size wise she looks about the same.
