What exactly is 50 * 50 feet ?
️️️️️ in the reviews give an indication of the quality. We don’t have harsh winters in the Netherlands, therefore I only know from reading you need a big coop or have to cover the run in winter to keep your chickens happy. 
is it bad for their coop to be bigger? Also yes I’m new to chicken care and it is my first winter period
It's not bad at all! But typically a coop is a fully enclosed building that can be made predator-proof, and then you have a big "run," or exercise area like your 50x50 space. My coop (I call it a hen house) is an 8x10 building that I can completely enclose and lock up at night. "Free ranging" means they are outdoors in an open area, often with no fences, like in a pasture or maybe a partly wooded area, with no or limited protection from predators. Those of us willing to take that risk usually have dogs on patrol to keep coyotes and foxes away, and we lock the chickens up in the coop from dusk to early morning to protect them from raccoons and other nocturnal hunters.
It’s the area their in all the time, she’s doing good actually
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 its 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.
