Hi I was wondering if anyone could help me, for some reason my male cockatiel (leo) won't let the female cockatiel (crystal) any where near the nest box.
They have been housed together for nearly 2 year ago now and Leo is usually plasid, in fact it's normally crystal that bully's him, I.e jumps on him, moves him out the way of the food untill she's eating, follows him around, now the past couple of weeks she's been showing a lot of interest in the next box, in and out ect and doing the mating call to him, however a few days ago I caught him in there for the first time and she was not happy about it, however since then he's completely took over it and won't let her any where near it. He comes out and charges at her if she's anywhere near, I can hear him scurrying around nibbling the inside but I've never seen him this aggressive before, they share treats but don't preen each other and he's quite a lot older than her. She's always been more interested in him than he has with her,
I know I need to keep an eye on them and they havnt actually been fighting as she moves out the way of him but he's awfully protective of that box.
This will be there second attempt at eggs and he was not interested the very first time ( for both of them ) it was unsuccessful as they wernt fertile.
Do I need to be worried. Is this normal behaviour, will he just let her in once he feels its ready for her? I've done a lot of research and if it carrys on I will split the cage in 2 and put him on the bottom but I don't want to do that. As it's a very big cage with ample room.
