I asked my mom to watch my birds this weekend because I had a wedding, and she brought her 11 y/o golden doodle. He likes to chase the birds here and there but never killed anyone. Well I get a call this morning saying there's all these dead chickens scattered about as if they had just dropped dead. We found 17 bodies but I'm missing 24; 2 or 3 had some blood in their beaks and I'm guessing the missing birds are still somewhere in the tall grass unless I'm falsely accusing the dog and something else got them. Tell me what you all think; my theory is that he pounced on them or gave them all heart attacks because they were all intact and 2 of them died hours later inside of the coop (internal injuries?). I'm not sure why I can't find the other 7 or so missing birds though. They are all free roaming birds but I've never had an issue before this except for a bobcat one weekend when the coop door frosted open.
