Our 3 hens have done fine so far this winter. We have them in a fairly generous size coupe with lots of straw that we freshen daily and of course fresh water and food. They have access to the outdoors but typically won't go out if there is fresh snow on the ground, so they haven't ventured very far for about five days. Our Barred Rock stopped laying eggs about a month ago (we still get 1-2 eggs a day from the other two hens), then she started losing feathers about two weeks ago. Now in the last two days her neck has become significantly bare, so I presumed she was molting. This morning I noticed she is actually a little bloody around her comb and a few spots around her neck, and I witnessed the other two hens pecking at her on several occasions. Is this molting? Is this normal flock behavior to peck or help preen the other birds that are molting? Should I intervene? I have started giving them more corn, seeds, cooked eggs, etc. And they have free access to oyster shells and layer feed. Thanks for your help.
