I’m new to raising chickens and currently have a mixed flock of 12-week-old laying hens. They share a pasture with my full-grown hens, but they don’t share the same coop. The adult hens' poop looks normal, but I’ve noticed yellow poop from the chicks. I started treating all the chickens with Corid a week ago, but I’m still seeing the same issue. All the chickens have been acting normal. Should I continue the treatment or take a different approach? I’d really appreciate your advice—thank you!
