Hi all. Yesterday we had a possom get into our coop, and he ripped a good chunk of feathers off of one of our hens (but thankfully didn't kill her). Looks like she just has the dimples where the feathers once were- no blood. Should I do anything with her to help get her back to normal? Should I worry about other chickens picking at her? Possum is no longer a threat... hoping no others get in!
