I have noticed the past two nights after holding my birds out in their house I have itchy forearms and a bite here or there. The first night I thought maybe it was just the chicken claws bothering me until I really thought about it. This is totally what I didn't want. Bites.. Does that mean I am not keeping my coop clean enough? I would think that fleas would still come in. Is this a common thing? What should my next step be? Any advice will be appreciated.
