i just got broad breasted poults. they are being raised alongside chicks. my question is, if i am not overly concerned with making them enormous (i am not, honestly. if they both live until thanksgiving and dress out at 16lbs each, it would be sufficient), when do i switch them off of starter feed, and what do i start them on? obviously my hens and roo eat layer feed. everyone also free ranges over about 1/4 acre (a half acre when they decide to fly over the fence to the front yard ). when all is said and done we will have somewhere between 9-14 birds total.
