Budgie has bloody neck
Our female budgie has had a bad neck injury for a while now. Previously I havent been concerned because a friend of ours who has had budgies before told us that it was probably due to the male budgie being too sexual with her (as in breeding too often). But her neck is just getting worse and worse so I've taken her out of the main cage to heal hopefully. She seems a bit lethargic too, not wanting to look at the others and just sitting there most of the day. Appetite seems o.k. Can anyone advise?
