Sorry if I sound so ignorant. I'm totally new on the Finch terrority. I have a cage 23" wide x 19" depth x 29" height. I have 1 male Zebra, 3 female Zebra, 1 pair Society finch. The male and 1 female are bonded and the 2 female Zebra are also bonded. The problem is, the Female who bonded wit the male get more and more aggressive toward the rest of the finches, chasing them everywhere and won't let them get close to any of the 3 nests. The cage is also setup with 3 large bamboo nests, 1 water dish, 2 food dishes, couple perches, a wood swing hanging from the top of the cage and a long paper tissue box with lots of hay in it. Am I putting too many finches there? Should I take the aggressive female out? The rest of the finches seemed getting along well. Only the aggressive one is causing trouble. I bought them from a local Pet shop. They said I can return or exchange if needed within first 2 weeks. I hate to do that as I already bonded with everyone of them. Any advice? Thank you!
