I have several bonded pairs of zebra finches that I need to combine into as few cages as possible for the Winter. I made the mistake of letting ONE pair set a clutch of eggs this Spring and now I have more birds than room. (Since then I remove all the eggs weekly.) I have tried my local pet store and they are not interested in my extra pairs and I have tried unsuccessfully to re-home the "surplus" over the Summer. I currently have five 30" x 18" x 18" cages, each with a single finch pair. This has been fine over the warm months in my unheated greenhouse, but the weather this weekend will be in the low 30s overnight so I need to move them into the house. I do not have room for all 5 cages so I need to know the following: 1) Can I put 2 sets of bonded pairs together in the same 30" x 18"x18" cage without problems? I can manage 3 cages in the house, just not 5. 2) What is the best way to put them together? Should I add some silk plants around perches to give the birds hiding spots from each other? Currently I have plain wooden perches, a few sand perches and several branches of apple twigs and curly willow in the cages for perching and housing variety. Should I leave them with nests or would it be better to have no nests during the "getting to know you" period? I enjoy the little guys and want to do right by them. When I first had finches I had males only, we then added two females and the more aggressive female killed the other girl when the groups were not bonded. Since then I separated everyone, got a new little female for the boy the aggressive girl did not choose as a mate and things have been fine. I do not want to lose birds again so if I can't rehouse them into fewer cages I will figure something else out. Please help me do the right thing and keep my birdies warm for the winter.
