The reason I'm wondering about the toys and perches more is because I've really been watching her behavior closely while she's in her cage lately, and I noticed she uses her mineral block that she has had for awhile to rub her head on a lot, which I read is is a courtship behavior. Also for a week or so before she lays eggs, she will generally nibble on a toy and then crouch under it as if inviting it to mate, and "go through the motions" . I'm thinking perhaps I should change things around when she begins to show these behaviors but I also worry about stressing her if I were to change things around too much too often. I am hoping to break the cycle in these behaviors, and that it will taper off.
