Hi, we have separated the roosters we are sending to have slaughtered and are wondering what we can feed them that will fatten them up nicely and improve their taste. We got day-old chicks at the beginning of May and they were all on organic chick starter, then chick grower and at about 20 weeks went to an organic layer mash. We are now back to organic grower ration for the roos (the feed store doesn't have a broiler mash that is organic) and are wondering if we can supplement with anything that will stimulate their appetites and help them grow a bit more, i.e., I have read that you can give them yogurt or cottage cheese? We are hoping to have them ready in 3-4 weeks. Thanks for any advice.
