Yesterday all was fine but this morning I put a bath in there and it all went pair shaped. The older male whose name funnily enough is grumpy Bob started attacking the other female who was in it first. She's disabled and can't get away easily and he got quite vicious. I took her and the bath out but when I put her back in her nest after a while he started chasing the other younger male relentlessly. If he does that to my disabled one he's just as likely to kill it since it can't get away quickly enough. There is plenty of room for more than one pair I would have thought?. I've had to take them out again which is a pain and into a temporary cage. Would it just be a spring nesting thing? I've seen more than one pair in aviaries before? The older pairs nest box that I put in their from their old cage The other younger pair have another box down lower where the disabled one can get to it. Before I put them in there I cleaned out the older pairs nest box. They pushed a lot of bedding and their egg out the door when they went back in. Yesterday they ignored the other pair. The middle one is their disabled offspring from last year. I'm wondering if because I changed the nest bedding they are thinking the other pairs nest looks more welcoming (it's the nest box they used last year) Oh and before anyone asks I have no intention of letting either pair hatch eggs due to the leg problems of my little grey.
