I've taken in two 4-5yr. old girls, a RIR & a Buckeye. They came from a good,clean, local home. I wanted to "warm the nest" before my chicks arrive in May. It's been 6 months since a predator killed my flock. The new/old girls are settling in fine, this is only their second night but they both have what I call water bottom, like duck poop. Their vents are in constant motion even when nothing is coming out. Anyone have an idea? Should I be concerned for the chicks? What can I do?
