Nambroth,
Thank you so much for helping me with this. Both the cages you suggested would work.
I have Zebra finches and I find it difficult to keep more than 2 of them together. Right now I have a pair together, two teen girls together and a pair with a teen girl.
In the cage that has the pair with the teen girl (their own baby, born in March) I find that the dad is super aggressive to the teen.
With the pair and their two teen daughters, I find the teens are super aggressive to the mother. I don't keep nests in the cages anymore - conflict.
I am trying to group the birds into fewer cages and be kind about the size of the cages. Ideally, I would like to have 2 cages instead of the 3 I now have.
The cage I am enjoying using for the pair with a teen daughter is a Majestic Gabled cage. Bar spacing .5 inches and 24X22X30 high. It is easy to clean and really a great cage.
I could put 2 birds in one of those, but again, wanted to reduce cages from 3 to 2.
