They should do just fine. Our four hens are just finishing the Fall molt. Only one is laying. One still looks pretty sad. But when the feathers fill in, she will look great with those nice new feathers.
My 7 hens are also molting. We normally go through a bag of feed in one month. The current bag is going to last two extra weeks. They are looking a bit ragged. Laying very few eggs. Otherwise they seem ok.
