The problem I am having is that the mother bird has killed a clutch before they were weaned and is now starting to pick on the babies. I do have an extra flight cage. Can I put the mother in her own cage until the babies are seed feeding solely on their own and then return her to her mate? The male has also been feeding this clutch and taking care of them equally. Any suggestions?
