Any good advice on how to take care of a Parakeet?

Yesterday we found him by our pool, just standing there. We think he was previously owned because his wings have been clipped and all he can do is flutter. We have never had a bird as a pet so we really have no idea what to do. He is our first bird by the way. He doesn’t seem fully grown and hes like a canary yellow color with some white on his chest. We are not sure what species of parakeet he is exactly so we don’t know how best to handle him. Because we found him stray, we are assuming that he flew from his original home or he was released. He’s really skittish if you get to close to him and he is kinda jumppy. Please post some decent advice.

What do I need to keep my budgies (parakeets) as healthy as possible for breeding?

What do I need to HAVE before they can even start breeding? Im really nervous about how healthy my birds are. And if I am even consideing to have them breed, I want to know what they need to be fed and what they need to be as healthy as possible. What is bad to do, and what is good to do with parakeets. What type of foods are best, and how can i tell if they are healthy or sick. Also, how often do i need to cut their wings, and is it necessary (also with claws)? I NEED THE 411 ON PARAKEETS CARE AND TECHNIQUES. PLAESE HELP!
