We are first time backyard chicken raisers, and we just moved our chicks outside into their coop a week ago. We have been letting them run around in the yard for the last couple days, but today we noticed our red sex link Frankie was limping and did not want to come out to roam. After looking at her foot, it looks like there is either a cut or a burn. There is some sharp mulch outside that could be the culprit. Also, we set up the heat lamp in the coop so they could transition to the cold, but I am worried she perched on top of the heat lamp and was burned. We want to clean the wound, but would love to have some advice! What do you use? Does it look like a burn or a cut? Will it heal on its own? Should we separate her from the other two chickens? Thank you for your help!
