Hi all, I have 7 month old layers and 9 wk old pullets. They are separated now. My question is: when I have them in the same coop and run how can I separate the food. I'm thinking of taking the layer food away, feeding all grower flock raiser and a separate dish of oyster shells for the layers. Problem is, how do I keep the younger chicks from eating the oyster shells beings they are not supposed to have added calcium? I'm really confused how to do this when they are all together. Any tips?
