Hi, I am an old-timer on this site but haven't been on for years - I have had 10+ years of successful chicken owning & I am stumped. I had a small flock of 8 easy-going hens, ranging from 2-9 years old. I just added 6, 17 week old hens. The hen on the bottom of the pecking order in the older group has decided she hates the 'babies' & she chases them. When they are in the pen together (I usually free range), the young ones are up on the roosts or on the top of the egg boxes, essentially hiding from the older hen. I integrated them a week ago & things don't seem to be getting any easier. Normally I wouldn't be that concerned but I am leaving for 2 nights, taking our LGD with us & having to keep all the girls penned up together. I am wondering if that is safe or if the crabby older hen could really do some damage on the young ones? I know part of the problem is the young ones are very timid breeds (Marans, Delaware & Welsummers), while my older hens are mostly Easter eggers... My question is, should I isolate that one hen while I am gone? I have an old henhouse I could put her into but I'd rather not if there is no danger. I have never had any problems with hens being mean to each other so I am wondering how bad could it get? Could I be risking the young ones lives or health by keeping the other hen in there for 2 nights & 3 days? I assume that eventually it will be ok but should I be pushing them together without any free ranging for nearly 3 days? Any ideas? Thanks!
