didn't want to post this in the emergencies forum, since I don't think it's really an "emergency"... my three, ordinarily VERY tidy chickens, have over the past few weeks, developed very poopy undersides. Their poop is normal, no diarrhea or anything, but I'm a bit concerned. Of course, trying to figure it out I googled and came up with vent gleet--pretty sure it's not that though. I want to preface this question with the fact that here, in Canada, we've had the coldest winter in the past 50 years or something and EVERYTHING is freezing--even the dustbath I made for them in a kitty litter tray (which they poop in and then even with my scooping of it sort of gets all clumpy and cold looking!). Their bums are otherwise fine looking, other than the crusty poop on the feathers, of course. They still lay everyday, eat like crazy, nose around and do other chickeny things. Oh, they're also extremely fluffy, too, which I thought might be why the poop is sticking around. Any insight on what might be up? If it's totally normal is there anything I can do to keep them clean or am I relegated to wait til thaw? Thanks in advance for any help!
