The size large is perfect for chickens, around 42 square feet plus nice vertical space for placing 2×3 boards across for roosts. I line the inside top and sides with hardware cloth to protect from raccoons. I have put an apron around the outside bottom also to prevent digging predators. I still move it over every week or so to put them on fresh grass. With young chickens i move it every day or two to prevent coccidiosis. For winter just wrap the north side with a tarp. Not sure about snow load problems though since we live down south.

Received the Pet Gazebo (medium size) yesterday in the mail, and it has to be one of the best purchases I've made. Not to mention, it shipped within just 2 days! (I don't have the Prime shipping, either). It has easy set-up instructions and assembles within 20-30 minutes. I put together the gazebo by myself with ease! Highly recommend this product to anyone who is considering purchasing. I spent hours researching for a durable, outdoor kennel that was safe, comfortable, and gave me the peace of mind that my lab mix will be secure in the kennel. The Advantek Pet Gazebo is by far the best kennel I've bought, and so happy I chose this kennel over the others I was considering. However, if you want to have it be even MORE stable and secure, you will need to buy the ground stakes separately.
There is a 5 year warranty on all the steel and nylon parts, which consists of the panels, arms and connectors. All of the other parts have a 1 year warranty. Overall, I am VERY happy with this product, and I might purchase another one here in the near future to connect to my current gazebo.

Nice size! Got a medium size for my GSD and she loves it even our puppy fits in there with her

If you happen to use this in the house and you have a muscular dog, modifications are needed. See picture, (4) 50lb weights were needed to keep my 110lb Rhodesian from moving it all around the room. Anchors are strongly recommended if you have a robust dog.

We show dogs and are frequently in one place for three days up to a week. This gazebo is fantastic for our three Australian Shepherds. We bought two so they would have plenty of room. Actually there is enough room in just one for them to be comfortable but if we are somewhere longer we put both of them up. The con is that it takes about 20 minutes to put them up and take them down. It is easy to do just takes awhile. The pros are that once they are up they are very secure. We could leave the dogs out and go watch the show or walk around and never worry about them getting out. Plus we made lots of new friends of the people who came by just to ask us where we got them etc. Great product! Highly recommend purchasing the bags to store them in.
