I was thinking about this when I was out with my girls this morning. I woke up to 14F and it's up to a whole 15F now (2 hours later)
See if they don't have a contact number where you can talk to a representative and inquire about if they've shipped any of these to your area. Perhaps the party who bought one from them will allow you to come by and take a peek. Cleaning and being able to reach everything inside is important to keeping your hens parasite free, healthy and happy. Some tractor/coops are a bugger to clean! The request isn't all that out-of-the-ordinary and most people who have backyard chickens like to show them off and tell people all about them. I've had half my neighborhood stop by after I got the larger coop - asking about it as you can see the peak and top of the roof from over my 6' privacy fence and it's location isn't where one would place a shed.
I could have gotten my Amish coop for $1,300 without the tack area - it would have been 8' x 6' instead of 8' x 10' What I liked about it was I can stand up and walk around inside and easily reach every nook and cranny to clean. There is a cute window in the back that opens - complete with a screen and the front door has removable lucite panels so in warm weather you can open one or both for great ventalation. We opted for the tack area to give us the extra 3 feet in which the girls can't access (they got an extra foot on thier side)so we can store most everything for them in there (feed will be in the house in the hot summer and will just bring out a few days worth at a time so it doesn't get funky) I'm a neat freak and also like to spend time with them, so I can take a short stool into their coop and have plenty of space to sit inside with them and hand feed them some uncooked oatmeal or whatever their treat of the day is. . .pet them and have shelter from the rain, snow, ice and wind. When it's nasty out they spend a lot of time inside and it's a comfort to see they can mill about inside with two roosts and lots of floor space, and eating area, so they don't get to bickering.
While I'm pretty new to chickens, you tend to learn some things fast - the term "Chicken" like 'don't chicken out,' or calling someone a 'chicken!' I totally know where this came from, as does everyone else who've gotten any - Chickens are 'chicken' Birds in general are, but chickens OMG. . .anything new or different they are suspicious of - sometimes waiting as much as a day or more to approach it. . .the first time I gave them string beans - too funny. . .and as much as I love my girls they aren't all that bright when it comes to a lot of things. I was on here all upset about how my girls wouldn't go upstairs in the chicken tractor/ark - and crawling under to catch them. . .wasn't gonna happen. Those birds stayed on the ground for a solid month - in the pouring rain even. . .nothing would make them go up the ladder/ramp and it wasnt too steep, and I had three in total all slightly different styles that I tried. They would walk up, look and go right back down. I put lights in, I opened one side and screened it in so they could see daylight in half of the top. . .no dice! When it was wet, they huddled together almost on top of each other and were soggy. I actually went to bed crying over it. So one month to the day later, they had the big coop. Because they are "chicken" I followed the advice of many on here and locked them in for 3 days so they would bond with their new home. . .on the first day I let them into their run, they slept outside - so I waited till it was good and dark and went out, caught them and popped them through their hen hole. After that they went in on their own. So, consider that if you have young birds, you might have to assist them if you are getting them in winter time, so they don't get wet and stay out (chance of frostbite).
My girls were 5,6,7 and 8 weeks old when I brought them home. . .now, 16, 17, 18 and 19 weeks old and how they have changed! Very sweet and friendly, although the Partridge Rock is a bit reserved compared to the others.
I'm sorry for the length of this, but I don't want you to end up with something you and your girls aren't happy with. Resale even for gently used will not get you all that close to full cost - so better to be certain than kick yourself. Since you've decided on spending that much and dont have to build a run, doing free range, and keep your number lower than 10-12, I'd suggest looking for a coop you can walk into. Like I said, mine without the tack area was $1,300 and that included delivery and set up (the place I bought it from is local though) but it's very likely you have something similar near you.
