separating

How old does a ringneck dove hatchling need to be before they can be separated from their parents? I have a one month old baby that is driving its parents crazy by asking for food, they do not want to feed it any longer, it is out of the nest and can fly.

My birds are in mixed groups together but in cages. Usually one or two couples or a single male is free in each room, I want to try keeping as many as possible free and together but I'm worried there will be discontent. What are the ways and reasons behind separating birds into groups? I'm...

Two of the birds which I purchased which will be breeders and prisoners are getting pretty friendly with each other. Here is my question: should I separate the cocks and hens until breeding season, let them play house and replace their eggs with dummies, or what? Thanks, Don.
