Buddy, my little blue petstore budgie and Willow, my green English budgie have been sharing a large slight cage (30" long by 18"wide by 36"high) and in spite of all my best efforts to eliminate strife, it isn't working. I have double everything - swings, high perches, low perches, food bowls, toys, clips for greens etc. Buddy has had red marks on his forehead. I assumed they were pin feathers because he is molting however I actually saw Willow pecking and attacking him last night fairly violently. I removed him from the cage to check him over and he appears basically okay but has lost a little weight. So Miss Willow has been installed in a large separate cage. But I am sad because I don't have room for both those cages and my parrotlet's cage in my den. I loved having Willow next to the sofa - she was always coming down to see what I was doing and beg for a treat. But in fairness Buddy was there first and I also love him. Maybe later I could get a couple of those 30X18X18 flight cages and stack them instead of the flight cage. I had already bought the cage I put Willow in but it was supposed to be an upgraded for my parrotlet so more cages are not in the budget at the moment.
It's good that you were able to detect the problem and have decided to separate your budgies. Despite the cage arrangement no longer being the same and your den not having enough room for Willow's cage, this separation was the best option when thinking of your Buddy's overall safety and welfare.
RIP sweet Tito (Summer 2008 - January 17th 2013).
You are missed and never will be forgotten.
Good for you for doing what you knew had to be done to avoid further stress and/or injury to Buddy. I think this will be a better arrangement despite the new locations and the situation. I have had to do similar things before as far as having cages where I didn't necessarily want them, but if it works out better for the animals and lets them thrive better and be happy, then that is what we have to do .
Well, the simple truth is that birds often have ideas about how things should be and they may be contrary to what we expected. On the plus side, Buddy never ate greens or pellets but he learned how from Willow during the time they were together. I just feel sad for him that he was distressed at all. But he will be better now and Willow will adjust. They are both very young - approximately four months. But Willow is in breeding condition - she has the brown crusty cere. They've never been affectionate toward one another even before her cere turned brown. Perhaps she is attacking out of hormonal frustration.
