I bought a bag of grower yesterday as I was getting chicks, got the chicks, find out they are cockerels so they are going back to the breeder, of course the bag of feed is opened as I have fed the chicks, I am getting 2 POL hens on Monday from her instead of these 3, my question is, CAN I feed the hens the grower if its mixed with layer? I have 4 laying hens already, and I hate to just waste this feed, I only bought a small $7.00 bag but still that is $7.00!
