My girls are all 21 weeks old, and doing well. Both Speckled Sussex have started squatting in the past 2 days, so I am really keeping my fingers crossed for some eggs soon! Went out today, and noticed their combs looked like this: Is that frost bite? If so, is there anything I should do about it? None of my others have issues, combs all look fine. We have a high of about 10F today, and the temps at night are usually around -15F below zero the last few nights, although -25F below is the norm. We had a few nights of -45F below zero as well. I have lots of ventilation in the coop, leave the pop door open on the 'warmer' nights (as warm as it can get in Northern Maine in Jan/Feb!!). I am more than ready for spring!! As are these pretty ladies!
