So this morning while cleaning chicken coop I noticed 2 small light brown insects on their poo tray. It didn't jump like a dog flea. It did look similar to lice. I rubbed under their wings with DE and sprinkled their run with DE as well. I rubbed garlic inside their coop too where they sleep. Will be spraying garlic juice in there too. If in case it is chicken lice I've been reading wood ash is good. Is wood ash from burned wood? Where do I get that? By the way I have given them Ivermectin about a month ago. Read lice feel nothing with that so won't help if it's lice on them. I found two but the way. Should I mix DE and wood ash (let me know how to get wood ash if it's from burned wood I got a lot) to mix with sand and make them a sand bath? any other things I should try?....I'm a new chicken mom and this is the 1st time in 4 months I have seen any creepy crawlies in their poo tray. I had a wood coop before and never seen any in there during my daily cleaning. I did make their pen longer so the new plastic coop on new lawn. Maybe that part if my lawn had some chicken lice. Thanks!
