We have five 18 month old girls, 2 RIR and 3 rocks. In April we got 6 new americaunas - so they're about 14 weeks old now. Everyone has met while free-ranging, but one RIR keeps chasing them and pecking at them. We tried to integrate them last week, and they did ok for a while. They had a small enclosure with separate food and water in the house which only they could enter and exit (too small of a hole for the big girls.) they were ok for a few days, then we found one of the youngins with a badly wounded head - feathers plucked and a spot that was completely raw. we removed the young ones, and put them back in their previous home - a large horse trough in the garage. The mean RIR even attacks us sometimes! I'm worried we'll never be able to have them under the same roof. Should i get rid of the aggressive chicken, or what? I can't keep them in the garage forever! HELP!
