My wife and I were given a rooster that had been in a bad home. Not bad as in fighting, the people who had the rooster were older and unable to care for their flock. They were giving their chickens away, my wife and I wanted a rooster, so we took one. The rooster is some kind of crossbreed, it is small with a red body and black tail feathers. The rooster is not socialized to being around people. The elderly couple were unable to spend time with the flock. The rooster is rather skinny as the owners were unable to feed the flock a steady supply of feed. He will probably fatten up quick since my wife and I keep the hens with laying pellets, free range and table scraps. I slipped the rooster into the chicken house last night. A few minutes after being in the house the rooster worked his way to the middle of the hens, then he started making cooing/purring sounds. The hens moved in close around the rooster. This morning there was no fighting, but I had to leave to go to work. There are 12 hens and the rooster. They have free range on several acres of land, so the are not bunched in close to each other. The rooster did not act aggressive when being handled. Before introducing the rooster into the flock my wife and I used pruning shears to cut the roosters spurs. The spur bled a little bit, but I did not want the rooster hurting the hens. The flight feathers were also cut on one of the roosters wings. The hens do not have their wings clipped. Besides diseases from the other flock, and lack of socialization, what kind of other problems are my wife and I looking at?
