Hi there, My Barred Rock's keel bone is very prominent, and she's never been wormed. I'd like to worm her just in case though... but my mom REFUSES to use 'medication'. She wants to use yogurt instead, no matter how many times I say 'we should really use Wazine or something...'. I know garlic prevents worms. I sometimes put garlic powder, oatmeal, and a little fresh ground flaxseed and make a mash with it, but I don't think that's working. I use very little garlic though. They also had pumpkin the day before Halloween. Is there any type of food that kills worms?
