We have 3 RIR's they are almost a year and were laying one egg a day till the cold weather started. One tarted molting early november but has most of her feathers bck now. Problem is her comb is very very pale pink and I noticed her beak is turning black or a very dark brown. I don't know if this is normal. This is my first experiance with chickens. She seems to be eating and drinking and acting normal otherwise. We have laying mash available at all times for them and I usually give them dried mealworms or grapes or oatmeal as a treat and somtimes I give them yogurt. They always have water available also. We put a small heater in the coop to keep them warm and have a light come on from 4-8 in the evening and 4-8 in the morning to simulate longer days to see if they will start laying again. Anyone have any ideas about what could be wrong with her? One of the others just started molting 2 weeks ago. Thanks for listning and any advice you may have.
