I'm thinking of buying them a red light and such, but I have a few questions. 1. What temperature must the place where they are laying be at? 2. How often am I supposed to turn them over and how many times a day? 3. What would happen if I DON'T turn them every now and then? 4. Once they hatch, when should I feed them. And what? 5. This one is a little of topic, what fraction to fully grown chickens go for? In other words, would the grown chickens be worth more or the same price as the eggs? And if so, what is the usual difference?
