Hello all, I'll be getting my first ever chicks in mid April and have been doing plenty of research in order to prepare. I've decided to go with medicated feed, but have been reading that this feed doesn't work like a vaccination - instead it works to limit the growth of the bacteria in their gut while they adjust to it. However, this requires exposure to the bacteria. So from what I've gathered, it comes down to two methods (or a combination of the two): Place some of the soil from your run in with the baby chicks or keep the chicks on the medicated feed once they start going outside and let the exposure happen then. Is there any reason not to expose the chicks to the soil while they're still in the brooder? Thanks!
