I know that when I was raising up my current little flock, I read that I shouldn't feed the young pullets/cockerals calcium before 16 weeks, or so. Of course, I started them on laying rations after that age, and keep oyster shells available as free choice. But, I have some new chicks that I will be integrating into the current flock in a few weeks, and am wondering how in the world I will keep them from eating the older girl's laying feed. Hummm, thinking just to place the hen's hanging feeder up a little higher? What creative ways have you managed this issue?
