I have one in my flock that lays a dark brown egg. I'm pretty sure that its a recessive gene to lay the colored egg and a dominant to lay brown so keep an eye out for brown eggs too. I wouldn't give up hope. Even though it is possible that a hen could never lay an egg its a genetic defect that only happens statistically 1 in 1000 hens so that's a .0001% chance that your hen will never lay an egg. I think everything will be ok, as you said its been getting colder. They kick into high gear once the temp gets colder so one option would be to throw them some corn, oats, rice, or whatever grain like that (I use a homemade varied mix of many grains and seeds) before bed and it will help them have energy when they sleep. Its also good for them to have a higher fat level in their diet so they have extra energy and a layer of fat to keep warm. Just my 2 cents lol.
