Fried Chicken, Anyone? Anyone?

Christmas morning we were greeted with a grim sight. The night before, we had been missing a chicken but figured she was just out in the brush and would show up the next morning, as often happens. But on Christmas morning, just after opening presents, I went to look at the goats through the window and saw a black lump up against the electric goat netting. I said, "Oh, no! Is that a CHICKEN?!" Dustin hurried and got dressed and went out to investigate, and reported that she was indeed dead and had apparently somehow gotten a talon stuck in the electric twine in the netting. When he moved her it actually smoked a little. Ahhh! What a horrible way to die! I can't decide if she died of electrocution or stress. What I don't understand is first of all, how on EARTH does one get one's talon stuck in a piece of twine? Second of all, in her thrashing about she should have been able to free herself. The chickens figured out months ago not to try to squeeze through the electric netting anymore. That first couple of weeks you'd see them try to hop through it and take off squacking. They quit doing that at least 2 months ago, and any who care to enter the goat pen now walk directly to the pallet gate and enter through the slats. On one hand, I keep telling myself that in following with the survival of the fitest, I don't want to pass on genes of a chicken too stupid to figure out not to walk through an electric fence after 3 months of practice, but on the other hand, I surely don't mind eating eggs from a stupid chicken or eating a stupid chicken itself! What a waste.
