I have a mixed flock of 5 barred rocks, 5 Easter eggers, and 7 silkies. All hens. They are ALL 20 weeks old, and everyone but the silkies looks big and beautiful, you can tell they are maturing and will be laying soon. But my Silkies are tiny little things and I have a feeling they are no where close. Everyone is still on grower feed until a see an egg. My question is: once one hen lays, should "everyone" be forced to eat the layer pellets? Will it hurt my silkies since they are so tiny and seemingly far from laying? Should I offer both types of food? Thanks for the help in advance!
