i am new to doves and have one single and two pairs, all in separate cages. They will have a large aviary, once my shoulder issue resolves. But one pair of ringnecks i got from someone have started fighting. They are a pair and have gotten along well in the two weeks i've had them. They have a nest, but no egg laying. Just today, i saw what i assume to be the male trying to fight with what i assume to be the female. Not horribly vicious fighting, but wings up for protection, some attempted pecking. i separated them but wonder what the issue could be. i do know they could use more room, and perhaps that is the problem. Would appreciate any insight or advice.
