If you are thinking about letting them breed, you need to get a gram scale, a brooder that holds temp in the mid 90's F at least and then make sure you have syringes and disinfectants. Amount fed and how often depends on how old the babies are when you are hand-feeding. Much of it depends on feel/intuition and what the babies are doing rather than a set schedule. You have a whole bunch more reading to do before thinking about letting your birds produce. Otherwise, its likely to just lead to loss of life. Get the book hand-feeding and Nursery management by Howard Voren and Rick Jorden. Its a little dated but its the authority on how to raise baby birds. Ideally, you let the parents feed for at least the first 10 days. However, if you aren't set up to be able to hand-feed from day one, that is like tempting fate to give you parents that won't feed or keep babies warm which gets us back to bringing a life into the world and then letting it die because you aren't prepared with the right equipment or skills to save it.
