Hello! So I got back from vacation today to notice something rather strange. Two of my four chickens have clearly defined naked spots on their rear ends. One of the other two has just finished molting and is perfectly fine. After just witnessing her molt, I highly doubt these two are molting. It could be possible, however. What I believe happened is a that that the final chicken (Who I have not yet mentioned) has started plucking feathers out of boredom. Before I left, I noticed her going after the two (weakest and lowest on the pecking order [the ones who are naked]) chickens and stealing their feathers. I believe she was likely doing this as we have had snow up to our knees for the last few weeks and they have not been able to go outside. They just stayed in their immediate run. As the majority of the snow has melted now, she now has the ability to go outside and, as a result, is not very interested in them anymore. Additionally, the two do not seem to be in any pain. No cuts or abrasions, just naked skin. I have also pet them there and they do not seem to mind at all. Finally, I am just wondering how long it will take them to grow their feathers back. I read somewhere that they will not grow back until they molt. Please share what you think the reason they are losing their feathers is, as well as how long it may take for them to grow them back. Thanks so much!
