Game camera is set up. Waiting to see what it is.
If it’s broody poo.... it’s unlike any broody poo I’ve ever seen. (And I have no broody bird. Just a momma with eight 7.5 week old adolescent barred rocks)
It doesn't look like bird poop to me. Where did you find the poop? I agree about putting up a game camera, Most likely whatever it is will be back. Good luck... A coyote.
A neighbor has goats. He really doesn't take very good care of them and every time they have a kid the coyotes will get them. Now he doesn't have a billy any more so no more kids.
