OK..i am not going to surar coat this so be warned... one of my hens had a build up of white poop on her rump feathers this morning. we brought her in and tryed to clean it up as best as we could with warm water and a paper towel. (she did get away from me and had a scare all around the house till she got caught). the only thing we noticed was the poop on the lower rump feathers this morning and so we took her back out and put her back in the chicken run. this afternoon i went out to give them some scratch grain and noticed her vent area was RED as it was a bit pushed out!! and there was more white poop built up on those lower rump feathers from it RUNNING liquidy poop? out her vent. i got her picked up and she also seems to have a chunk (pea sized or so) of white poop dry looking/feeling and stuck on the side of the vent area that is sticking out. I got her a bit cleaned up and was trying to start working on that stuck part and she all of a sudden pulled the vent back in like it is supposed to be. we have her in a cage by herself right now. she took another poop and the poop was a bit hard and dry. the vent stayed out again and the white dry/stuck part is still there. in fact the poop she dropped did not even have the "white" part. i gave her some water with a drop of A.C. vinengar in it and some feed and scratch grain with some olive oil and a spoon full of yogurt in it. OK...THE QUESTION NOW.....what do you think is wrong with her vent? will it (vent) start working "right" again once she gets that dry white poop part out?? should i keep giving her these things?? AND could she have had an egg break INSIDE of her when she was flapping all over in the house when we were trying to catch her???? ANY HELP on this matter so i may have an idea as to where to go from her is greatly appreciated. thanks so verrrry much.
