We've now lost three more chickens, but these were the ones already living outdoors.
Last night we came home to find all the chickens but one piled into one dark corner of the chicken house. The one that wasn't piled up with the others was standing in the opposite corner, minus a head. It appeared that it had stuck it's head through the chicken wire (how does that happen, BTW?) and something had snapped it's little chicken head right off.
Today the same thing happened to two more, sometime between the hours of 9 a.m. and 2 p.m. This evening when we went out a hawk was perched on the fence, eyeing the chicken house. It seems we had found our predator.
Jay has since put up a second wall of chicken wire.
The moral of the story is, if you're a chicken, don't try to get through the chicken wire, even if the weeds on the other side look irresistible.
I don't feel too sad about these guys. I think it was natural selection at work.
