I have a male Parrotlet named Rico who recently lost his mate. It was really sad and unfortunate. I just got a new female that is the same age for him to bond with. They are both green. I had them in cages beside each other and they were sitting on the side of the cage closest to each other. So I let her fly out and she went right to his cage. He did not attack her or anything. I eventually put her in a cage with him that was unfamiliar to them both so that they would not get territorial. She will cuddle and preen him but he will not do the same to her. He was not letting her eat the millet I had in the cage and they began squabbling so I took it out and the fighting stopped immediately. But they are not sitting on the same perch and I'm not sure what to think. Are they bonding or are they just tolerating each other in the cage? Should I take her out or leave them in together? He has not outright attacked her but will peck at her feet a bit (it sometimes seems a bit rough) if he does not want her to do something or go on a certain perch. But then he will sometimes stand on the perch with her and let her preen him. If any of you have any advice on how to proceed it would be greatly appreciated.
