One of my girls stopped laying 8 days ago. She seems happy and healthy so I thought it was because of the weather here in Michigan. Today one of my 2 hens have appeared to start molting due to the amount of feathers I found. I'm assuming it is the one that stopped laying. I am very concerned because they are still in their tractor coop which is not any warmer than the outside temp. We JUST began building their insulated coop but who knows how long it is going to take to finish. Is there ANYTHING I can do to help stop the molting process?
