I'm a total newbie. What do you think happened to her feathers? Is she starting to molt or did her feathers get stuck? All my girls are very non-abrasive so I don't think she got Ina fight.
I have a very small coop, 4 chickens, and a kennel run for them. What do I need to do to prepare for winter? Heat lamp? How much light? Etc...just not sure where to start.
