I have 6 hens...~1.5 yrs old. All of my EEs and 2 of my BRs have all molted and have already started laying again. Then there is Dot, my other BR. About a month ago she got Sour Crop (she's all better!) and while she was in the house she started molting on her chest. Well, the pin feathers are all just about grown in, but she hasn't lost anymore! She is acting like she is in a molt (lethargic, not eating as much...exactly the same as all the other girls did), but she still has all of her ugly broken feathers on her back and tail (or what's left of it!)! I don't think she is sick, but it seems her molt is "stuck". It is nearly February and she STILL hasn't fully molted! Most of my girls were done by November...maybe the beginning of December! Oh...could weather affect it? We've had an exceptionally warm January (been averaging high 60s during the day and mid-high 30s at night...occasionally at freezing).
