Three days ago, as I started my morning routine of getting my 5 birds out of their crates on the back porch to spend the day outside, something creepy ( literally) happened. It felt like crawly things going up my arms and ending at the top of my head. I inspected myself and all the birds and found nothing. I bought some Poultry Protector and sprayed them down rather inefficiently (one of them is a guinea). My son's vision is better than mine so I had him check. Nothing. I'm still getting the reaction when I pick them up. The itch lasts till I take a shower. Any ideas? I don't want to start a chemical war without a diagnosis.
