Hello, I am about to get some African grey geese. Long story. I want to get 2 females and a gander and have been reading some things about how to tell them apart. But the lady said the females have orange bills, and I have searched all day online without finding any verification of this. I think either the ones with orange bills are immature and/or crossed with something else. How old are geese before they STOP laying? Some of her geese have what seems to be "wet feather" and one drags her wings. Is this coccidiosis, or worms? I want healthy animals. There is little choice here in Hawaii, and most poultry can't be shipped here, so I am trying to pick out the best of what is offered. I am going to get them this afternoon....can any one help?
