Just wondering when i should stop feeding the medicated starer grower to my chicks they re about 1 month old now and fully featherd even the bantams have mowhawks so cute.
Don't stop till they are at least 18 weeks old or laying. You can change to unmedicated about 12 weeks old since by then, they are probably somewhat immune to cocci, if that is your concern, them starting to lay while on Amprolium; however, that is not an issue at all.
