may look cute...... very efficient killer... and if it decides to kill 5 chickens in a day it totally will! size means nothing!that stoat is really cute, he could not have killed 5 chickens in one day so I'm really glad you caught the raccoon a much more likely suspect.
The stoat is stealing your eggs but he is too cute. Hope you can secure your coop and keep everyone happy like that, the stout will not be a threat to freeranging chickens during the day - its only the size of a squirrel.
