I've had chickens for years and they always free ranged. Anyway, I never wormed them or paid much attention to them unless obviously injured. They were always great layers and healthy! But now, I've gotten into chickens as a hobby. I give them names, treats, spend hours talking to them and taking pictures, etc. Recently I noticed they combs all seem pale. They seem fine and are 6.5 months old, laying and active pets. What other signs are there to knowing if they have worms? Or should I just worm them for good measure?
