3 males Zebra finch
Hello, I had a pair of zebra finches who got two babies, but lost mom just after the chicks hatched. Dad successfully raise the babies. Both are males (starting to get zebra lines and black belt on chest). We are getting to the point where babies should be separated from parents. However, dad would then be alone and depressed. He is bounding with the babies, especially one. What should I do? Can I let the 3 males together if they seem happy? And if dad seems to pair with one of the young male, should I get a new bird to pair to the other baby male so he is not left out (I would assume an other male)? They are in a big flight cage (18x18x90) with plenty of room and perch.
