This evening we put our 4 chickens in their run, about an hour before they were due to head into their coop compartment for the night. When we went out to close the inner door, our ameracauna was bleeding on her comb and beak and wouldnt move. It appears that the coop perch had fallen down. We are not sure what happened. We picked her up and wiped her off and thought we'd try and put her in the coop to bed because when we were cleaning her up, she seemed to be falling asleep. We had offered her some seeds and water which she took as we were cleaning her up---but, when we put her in the ground to make sure she could walk, she laid on her back, and didn't try to get up. We have no idea what to do--its 9 pm here. We wrapped her up and took her inside with us. We are new to chickens and this is our first flock. she's about 18 months old. help any advice?
