I had a similiar incident while I was living in a rented house with some friends. I went away for a weekend and came back to a live chick...yes that's a baby chicken in the enclosure with my BP. I was SO PO'd. But remember IF it's the first time try to stay cool headed. I only had to tell my buddies once and that was it. They just don't know that our "hobby" has alot more to it than they can fathom.
