Well, as we are fairly new to chickens, we made about every mistake possible when integrating two new pullets to our existing flock of three, very competent layers. We didn't use strict quarantine procedures (read about that a little late); we added younger hens, rather than ones of the same size; and we added the new ones while our hens were molting (one of them is going through a hard molt). Boy, do we feel stupid. However, we have tried many things over the past month and a half, to no avail. On the positive side, they free range together and they sleep together. Bed time and first light is stressful, and often ugly, however. We did have the newbies mostly separate for a week. Then they began free ranging and sharing the hen house as well as the run. My alpha hen has accepted them, but not my two RIR/Delaware hens. They continue to be excessively aggressive, occasionally drawing blood if I am not quick. I recently just gave the reds a four day time-out, hoping to increase the bond between the alpha and the newbies, while taking the reds down a peg. That didn't work, as the reds are right back at it. Weeks ago I built a nest box addition to the hen house and a roost outside the door to the hen house so my newbies would have places to escape more safely, which did help, but didn't solve anything. So now I either build them their own hen house and fortify the run for them, or I return them to the vet/outreach center where I got them (all five came from the same place, by the way). One of the new ones is a beautiful australorp cross and the other is at least part bantam (probably some wyandotte in her, but not sure). They are such pretty hens, and the australorp is very sweet and enjoys snuggling. Her docile nature doesn't help her with the bullies, however. Luckily the two newbies are great fliers and have no difficulty getting higher than my hens, if need be, for a quick escape when ranging. I guess I just need to make up my mind, but it has been very helpful to read what others have tried, so thank you for that. I can't believe the amount of chicken stress I have felt, trying to make this right. Silly, I suppose. I feel like a bad mama hen who can't seem to control her chicks. Bummer that the "sorting it all out" never really happened. Again, my fault (and a bit lies at the feet of my crabby hens, whose position has never been challenged). Thanks for letting me vent. I'll decide this week.
