I have 2 silkie hens, and I have been told to give them higher protein food so I have been giving them multi flock starter/grower 22% protein. I recently changed food and bought Agway's new hearty hen layer and a bag of H and H soy-free non-GMO starter. I need to board my rooster at a different farm and will have to buy him a seperate bag of feed, so would the silkies do good on just the hearty hen or is it too much calcium? The hearty hen has 18% protein so not bad for a layer, also is soy-free and has flaxseed. Also, is it okay for my rooster to be eating it? He eats the mixture of the hearty hen and the starter. to add, one hen just started laying, the other is 6 months old and hasn't started yet.
