I have some 2wk old silkies and some 1 wk old silkies. I also have one hatching today. I've had the chicks on non-medicated feed since they hatched. Based on several posts that I've seen on here, alot of people use medicated until they start laying. We bought some medicated feed yesterday. Do I need to slowly integrate the medicated feed to the babies or can I just start feeding them the medicated? Will it shock their system if I switch from nonmedicated to medicated? I don't want to do anything that would hurt them. Thanks!
