I have been feeding them Purina Layers feed and also clam shells (about a hand full per 7lbs of regular). Should I stop with the clam shells? The eggs are seriously difficult to crack open... I didn't notice till I got some eggs from a friend that were fertilized and all of them wouldn't fit under my broody hen... So we ate them. Also, the broody hen should hatch out the chicks on the 3rd of next month. I kept her in with the others and got some flock grower feed for the chicks. Is it ok to feed them all the flock grower? I read in another post that you can do that and use the shells and the chicks wont eat the shells... Also #2, I just got a new rooster, is it okay for him to eat the layers feed? Also #3, what is the medicated feed? Should I use that sometime? Thanks.
