i am about to attempt weaning my first round of youngsters,they are 29 days old,i have been introducing them to the drinker over the last few days which has been succesful, and all of them are still being fed by their parents,a few of my hens have started laying their second round and i felt that now would be a good time to start.is it best to let the youngsters discover the feeding troughs themselves or should i introduce them to corn myself.i have a young bird mixture to feed them with.
