My slow broilers came from Welp Hatchery and have been very healthy and growing great. I have had them on Flock Raiser since they arrived. The hatchery said that they should be changed over to a chick grower at 5 weeks until butchering. Has anyone else had these slow broilers and can you tell me about your experience in growing them. I don't mind changing food if it is really the thing to do. I also have 9 5 week old hens that are also eating the flock raiser. I really don't want to have to find a place to store two different kinds of feed. Especially when I am assuming that the hens will need layer feed when they start laying. Nothing like have dibs and dabs of extra food. Also, how old were your broilers when you butchered?
