I have about 40 or so chickens. The oldest are about 22 weeks and are just starting to lay. The youngest are 4 weeks and I have just about every age in between. I am currently feeding unmedicated chick starter and a bowl full of scratch grains thrown out once a day. When do I switch to layer feed if I have a flock of mixed ages?
I hear so many stories of people feeding layer even though they still have young chicks eating the food.
