I'm feeling like a total idiot. We raised 7 hens from chicks (got them from hatchery in April). I'd posted about our four big girls getting stolen from the coop. An acquaintance of a friend had a huge number of young pullets she'd raised from chicks from a hatchery... I've never seen so many chickens in one place. All of the chickens had pecked tailfeathers, and we felt really sorry for one pullet (with no tail feathers) and brought her and another pullet home. I am embarrassed to admit we didn't even think about quarantining them. In hindsight, we can see all the reasons for doing so, but at the time, just didn't know. They've been in the coop with our barred rock and two bantam hens for about a week now (we let the older girls free range out of the coop all day, and they are really only together at night, and seem to be integrating fine as far as pecking order). But they've probably passed on anything they might have had. So my question is... Anything we should do at this point to protect them all? I'd posted questions about treating the pecked hen and about dusting for mites/etc., but wondering what we can do besides sit and wait and hope? I promise we've learned our lesson and will quarantine from now on!
