Feed them all an 'all flock' type feed....with oyster shell in a separate container for the layers.Previously I was filling a trough with layer in the coop yard, letting the 1 year olds out they would eat a little and head out. Meanwhile, id be in the coop with the pullets and filling another trough of grower. They would usually devour it. Then id let them out.
I guess I was trying to make my job easier somewhat ,But I will go back to the old way for now.
