So I have 3 hens that have been raised together and love one another and are about 8 months old. A Buff Brahma, Salmon Fav, and Lav Orp. I have 4 new hens that are about 4 months and have been very ready to move from their huge box in my garage to the outside world. We bought a 6x8 wire dog kennel and set it up near my other hens 8x12 run/house combo yesterday. They could see each other and barely get their beaks to one another but that was it no contact. Last night about 8pm we put the new girls in the hen house with my current flock and they just all settled in and went to sleep. Today I decided to just try and let them all out together since I had a few hours this morning to watch them and it did not go well. The 2 that actually came out of the house were immediately attacked by my Brahma and Orpington and the faverolle could have cared less and was doing her own thing. The Orpington was the worst and kept corning 2 of the girls and jumping on them and pecking them. So I just gathered the 4 new ones back up and put them in the separate pen thats up against theirs so they could not get to each other! What am I doing wrong? I do not want them to get hurt or stressed out, did I not give it enough time? Should I keep them in the separate pen for awhile longer?
