I just noticed that my banty cochin who has been sitting on eggs for a two weeks, has lost weight and is weak. when i picked her up i noticed the plumage on her rear had completly blocked the vent. She essentially has pasty butt. I cleaned most of it out and trimmed the feathers around it. I'm just wondering if i should allow her to stay on the eggs. i also have two Old English hens who are broody but havent sat on any real eggs... should i try to give one of them the eggs?
