My husband and I found 2 different stool piles of stool with blood. Is that normal? An oppossum got into my garbage and there was a lot of debris as I cleaned it I noticed she got a hold of a broken bone. I chased her through the yard trying to get it back but she was quick. Then the next day we saw the blood. Can that be related? Also will cats harm my 12-14 week old little chickens? They've been sleeping in an inside coop because where we live there are So many stray cats and oppossums I'm scared they'll be harmed. At night the oppossums emerge but these feral cats are around daily.
