I was told by a friend that you can give chickens cat/dog worming tablets and they will do the same effect? I'm not an expert with this and this would be my first flock of hens since I was a kid, so any help would be much appreciated. If I can't give them dog or cat worming tablets, what should I buy for them? I imagine it would be chicken worming tablets haha but I'm really not sure. And what schedule should I be worming them on? Is it a monthly thing or..? Thanks~!
