HELP, I don;t know what I'm doing! I have 10 hens and 5 roosters; they are all 5 weeks old, and almost finished a 50lb. bag of chick starter. When do I change to another feed? And WHAT do I change to? Also, they will all share the same coop until it is time to butcher the males, I can't separate the feed that I'm giving them, because they're all together. So WHAT can I feed both until butchering? Also, (excuse my ignorance, I'm a first timer) I don't know what age or size to butcher, and does that time coincide with when the hens begin to lay? I'm concerned about what to feed when, and to whom.
