I have 3 5mo old hens that just started laying this month, 4 older hens i just adopted that arent laying rite now, and a 5mo old rooster... i provide them all now with farmers best grower feed along with oyster shells but its time to buy a new bag of food and i know the girls should be getting layer pellets/feed but what should I do about my rooster? Isnt there too much calcium in the layer feed for his body?
