I have my chickens in their coop because I'm not sure when they are coming to harvest the weat feilds. I was told this week sometime. So I sent out this morning to do my chores and saw a couple hens out. My thinking is the goats opened the door again. But when I went to check they did not. Somehow they broke a peice of glass out of the window and flew out. All chickens amd peeps are here. I had to put the one hen down. Her bottom beak was ripped and hanging there. The glass was broken on the ground on the outside of the pen. The glass was little broken before, enough that if someone locked you in you could put your hand through and unlock yourself.
