Well, whatever it was came back and sort of got the other one. We came home from work yesterday and the other chicken was outside the pen, but the door was closed. I found a small hole which might be where the critter made it’s way into the coop, or ours got out.
Normally the chickens move around when I come to them. They are rather hard to catch. This one just stood there and let me pick it up and look it over. It was pretty banged up. I won’t describe it. But it wasn’t dead. I had to put it out of it’s misery though.
Strange feelings of guilt about the life of a chicken that died because of my lack of observation of this hole.
