what to do? we now have eight buff orpington hens (hatched may 07) since two have recently been killed by the rest of the hens. they pecked them to death. we saw the pecking begin last summer and we went to tractor supply and they sold us a purple substance to put on them. that didn't work, then we went back and they sold us a black tar like product to put on the wounds to heal and discourage pecking. seemed to work okay. but suddenly, they started pecking on everyone again. we separated the three worst ones with injuries, but of remaining, one hen was killed last week and then a second hen was killed two days ago. what should we do? We want a buff orpington rooster but none are available. would that put order back into our hen house? We also have them under a roof and in a 14 foot by 8 foot pen and we're going to expand it to include an outdoor area, still completely fenced in top to bottom to protect from predators. hoping that the activity outdoors will calm them down. we can't let them run loose in our area. too many coyotes.
