So I have 11 chicks that range in ages from 10 weeks to 14 weeks. Last week I added two layers to my flock. Integration has gone superbly well. But I have no idea how to handle the feeding. First off, I switched them all to dumor grower:finisher right before the hens were added. Is this a medicated feed? How do I tell? Someone told me that you cannot eat eggs for 2 weeks if the hens are on a medicated feed. I cannot find anything on the label or online. So frustrated! Secondly, if it is medicated, what should I feed the mixed flock? Also, what about oyster shells--aren't chicks not supposed to eat it? I have no way of separating them. Will the layers be ok without a layer feed until the little ones are old enough? I read that chicks shouldn't have layer feed until 18 weeks. Please help!
