Hello, I have 4 parrots all of them have been together since 2017. All were babies with only intervals of two week difference. Three males one female. All of them loved each other. But out of the nowhere two of the males started fighting (Im not sure if it is because of the female, she was laying eggs and in a breeding state, first time) These two males used to cuddle together, all of them used to sleep together in a box. One is a yellowsided normal green cheeck and the other one is a suncheeck (greencheeck too, thats the name of the color mutation). That time the normal conure hurt the suncheeck from the beak and he was bleeding. one was inside the cage and the other one was free around the house, they fought through the cage bars. I separated and they didn’t see each other for 2 1/2 months until today. I thought they forgot already but apparently they didn’t. They wanted to fight. It seems like they wanted to kill each other. Will they ever be able to be together again? It seems they have a pretty good memory and after that long they remembered they wanted to fight. Or they will never be able to be together? Has anyone experience this? What can I do to get them be close as before? I dont know what to do.
