I am new to raising chickens (got my 4hens beginning of summer). I have 2buffs, 1 red & 1 Leghorn. They went through fall molt. I added plenty of protein to their diet and they recovered nicely. I winterized the coop for drafts and add clean water daily. They are pretty much free range and I see no signs of stress. I have a heater that keeps the water from freezing but after reading up I do not want to add artificial light/heat.I am perplexed about the total lack of eggs(since molt). Is this normal or should I be worried. They are all about 4years old.I can live with no eggs I just want them to be healthy. They have become more like pets.
