My birds will eat them, talk about chicken football! game on if they rustle one up! They seem to be finding a lot right now, may be due to all the clearing of brush we are doing.
I agree, I kept a few as pets, very good snake to have around. Very docile and made great pets! That appeared to be a young one.

Yikes! Rats are terrible to get rid of, Dad had some in his barn up north, we had a hard time getting them gone. Didn't help with the cats food out there either.
He couldn't feed them outside because of the raccoons and skunks.
He had issues with muskrats too, and they are pretty aggressive!
I bet that is fun to watch.
