Hello all you veteran chick raisers! This is my first broody-Hatched batch of chicks, scheduled to hatch in a few days I'm wondering if I should be planning to vaccinate the chicks and/or give them medicated feed or not? Or, do they develop immunity etc. Via momma? I've only ever had full grown birds and chicks that came from the hatchery and I raised them under a heat lamp. Not sure how much/little to "interfere" or just let nature do its thing. Any thoughts here? Thanks!!
