I'm new to fowl and want to do right by them. I'm panicked as there are creepy crawlies on the peacocks heads! What is safe to use? I've read so much conflicting info-can kids get it? The bugs have to go! These peafowl have never been wormed. Nervous about using cross species wormers. Please advise which one is best and how to administer. I'm also wondering where to buy diatemaceous earth, and how to use it in my flights. Any good online sources for poultry products? I realize you're all chicken folk, but I hope someone can help. Very grateful.
