I've had single hens attack them and entire flocks of hens attack them. I watched about 6 hens come in one time and all hell broke loose as they just beat the snot out of my DSD. The good news is all them PO'd hens brought in a LB running. The bad news is soon as they saw the LB, the hens all left the hen and went to the gobbler who was safely out of my range and took him away. Very exciting morning with the exception of not pulling the trigger. PS. I've had several single hens just come in and peck my DSD on the top of the head and then walk off.
