I bought a SF Yellow back cock gouldian a year ago and he was the only YB out of 30 normals I have, he's not bred at all since I have had him, 2 weeks ago I bought another SF Yellow Back Cock and suddenly the first one & his hen have gone to nest and are sitting on 5 eggs

maybe he didn't like the competition and thought he had better get his act together or off to the pet shop.
