This is the second winter for my 5 hens (golden comets) and egg production went way down about 3-4 weeks ago when it got very cold. This is in Vermont. The last two weeks they are losing a lot of feathers and kind of lining the coop with them, which I thought might be for extra warmth but now see (from other threads) that they are probably moulting. The question is, can I add light to the morning on a timer if they are in the middle of moulting, or do they need to finish this process first? Also, how do I know when they are finished Moulting? Thanks!
