I have a 4 week old Roller pigeon. Eating on his own. How much should he be eating? Don't have anything to do the cc measuring. Slowly removing the soft peas and corn and turned over to racing seed mix. Eating with no problems. Just need to know how much. Should he start flying around 5-6 weeks? And.. finally.. what is a good age to return too the coop? Put him in today for 2 minutes and the others tried to peck him away. Too small and would be injured.. Still learning how to walk.
