I have 10 silver lace Wyandotte hens I bought them from bomgaars when they were just tiny little things and that was middle of May it is now the middle of August. I have them on starter/grower feed when can I switch to the adult laying hen food?
I would start switching at 18 weeks for that breed. Mix 50/50 start and grow with layers feed for two weeks. If you want to switch to pellets, mix them with scratch grains. Or just toss pellets on the ground as a treat for a couple of days before mixing with the old. Chickens are cautious with new feed. CC
