My 5-week old chicks are in the house, unvaccinated, and not on medicated feed. They've got a container of outside dirt to play with, but sooner or later (hubby says sooner!), they've got to make the move to the big girl coop. I've read some conflicting posts, and I'm confused about the medicated feed. Does the medicated feed kill everything so they don't build any immunity? Or does it just cut down on the magnitude of infection so they CAN build up their immunity? I must assume they'll be exposed to more stuff out in the coop than they're getting from their dish full of dirt. Should I have them on medicated before moving them out? Or will that just postpone the problem, and I'll be dealing with coccidiosis as soon as they come off the medicated feed? Am I just over-thinking? Thanks for any advice!
