I have two 18 month old hens, one of them has started a very heavy molt, she has bare patches in various places. The hen house is warm and dry but both birds spend all day free ranging my large garden. They have a constant supply of layers pellets and I also treat them with grapes, mealworms and cooked rice, and also a scratch mix of cracked maize and various table scraps. We have a severe weather warning for the coming weekend with snow forecast, and I'm worried about the hen that has the bare patches (Mabel) might get too cold. She is a RIR, her companion June is a Buff Orpington and is showing no signs of a molt despite being the same age. Should I be taking action ? is there anything I should be doing to help Mabel keep warm during this cold spell ?
