I have 8 hens, 1 rooster, and 1 guinea hen, they are 7 months old and have a wonderful routine. My friend needed an immediate home for 4 (7 months old) that I originally gave her when they were 3 months old and 4 older girls. Predator problems. I have a tree farm and this is the busiest time of year. I have a dog crate in my coop, 6 of them went into that last night with one old girl and one young girl sitting on top. This happened after monitoring for an hour to figure out where to put them. This morning I came and left the 6 out of cage. Well the young one that was on top of cage was amongst mine and already had a bloody comb. I sat in outside coop for awhile, there is a lot of fighting, two of mine have a bloody comb. I put what appears to be a very aggressive older one into the dog kennel inside. However, this is disrupting the quiet time for egg laying in the coop. I know this is not the correct way to introduce new chickens, but I don't have a separate area other than my dog crate, and no time to rig up something now. Any suggestions that would help this transition? How long before they will become friends?
