I was wondering about diamet.....earth. Food grade. do I use that for worms? I bought some ivemec powder from Cultlers. for pigs it says but ad says poultry too. do I have to toss out the eggs for awhile after I use ivemec? Country max sell 50# bags of diamet...earth. Can I just spread it around the yard? inside the coop and nest boxes? Maybe the areas that retain water when it rains? Ive noticed a couple of coughs from some of the birds while eating crumbles in the yard dish and I've been watching and listening at night but haven't heard anything chronic and would like to avoid/prevent any problems. My Del roo is moulting and he's one of the ones I heard cough. Which begs another question why only him moulting? They drink from puddles in the yard so I'm concerned about worms. They have water but they still drink from the puddles. On occasion.
