Hi all, I am a novice breeder and I currently have 9 budgies in a large outdoor aviary. I have one breeding pair at the moment that have just layed 5 eggs and was wondering if I could hand rear one of the chicks. I have been doing some research but would love to hear any advice from you guys. Things like what age to pull the chicks and how to keep/house the young budgie and any other important things to know. Thanks in advance
