She's adorable, I love my Sapphire Gems. Seems like she's just had a bad comb bleed that made it look worse than what it really was. They are still young pullets. But I just want you to be aware you could potentially end up with some bad bullying and feather pecking with them being in that area all the time. That's really not the ideal size for 18 chickens. As a coop to sleep in yes it’s plenty of room. During good weather do they get to range outside of the barn? I know you said they get about two hours out in the barn to scratch around because of snow right now. How much snow do you get? Mine do just fine in the snow but we usually don't get more than 5 to 6 inches at a time when we do get snow. So I shovel trails for them and they go about there day.
