I like being prepared, so id like to make a basic list of must have medicines. For mites, lice, common cold, scratches. Common preventatives will help too! I live far away from any supply stores, so id like to stock up before my chickens show any signs of sickness (i dont want lice to have two weeks to fester while i wait for my amazon package!). Please list your go-tos and must haves Thank you!
