A few days ago I found that 2 of my birds,(A golden Wyandotte, age 1yr, and a Barred Rock, aged 5yrs) had a quite enlarged abdomen/bottom/under the vent area. Its squishy, and feels like a balloon, and its so big, they have to waddle to get around. They also seem to have trouble going to the bathroom, and when they do, its quite runny. they are eating and drinking normally, (layer feed, a corn/oats/protein mix, oyster shell and a few garden treats)but they aren't near as active as usual, because they have to waddle around. After I was debating what to do for a day or so, the GW's belly just deflated all of the sudden. That morning I went out and her belly was almost normal size, only now its very messy, and has poo everywhere.
But she seems to be feeling a bit better. The BR, on the other hand, is the same, if not worse. Her comb has turned a purplish shade, and is shrunken & droopy, and her belly/bottom is ginormous!!!
Does anyone know what this is, and how I can help my sweet chickens?
