I have a male and female budgie over 1 years old.The female is tame.I put a nest box in with them at the start of January but they won't even go in it. They live in the house so it's always at least 65 degrees Fahrenheit and there is always 16+ hours Light. They have a big cage and I give them millet and lots of fruit and vegetables. The female is in breeding condition as she has a crusty brown cere. The male has one bad leg that he leans on. I've been finding blood on the perch and on the males head. If I seperated them and got a new male he would be only 2 months old so I would have to wait another year to breed them. Any advice greatly appreciated.
