A predator visited my chicken coop on July 28th. It used a brute force technique against the electric fence. Simply jump over, putting the belly on the fence. The electric shock power was week after heavy rains at night. It could be a raccoon, but the fact that it came by the road and clear experience with jumping over fences points to a domestic dog.
The damage is great: 4 white hens, 4 brown hens, 2 silky hens, 6 ameraucana chicks.
The most bitter loss is a silky hen called Granny. She was a professional babysitter and accepted any orphaned chicks. She bravely died protecting her foster ameraucana chicks. I had for her a lifetime job…
From the good side, 10 hens and the rooster survived somehow. Also I got a delivery of 12 meat type chicks the same day – for other predators… They all went to poor Puffy.
