Well the coop looks only big enough for 2 large birds. I'd say if you have more than that, than no. You need 4 sq. ft. per bird for coop space, and 10 sq ft for the run. It does look modular, so you could add on.
From what I've learned, the winters here in Indiana won't be a problem, some keepers have them outside in the coop with no heat, in negative double digits. For the summer, they need some shade and air circulation, so I may add a fan for our coop.
IDK if the farm would have good birds, but if you look at the stock they have you could probably make an educated guess, seeing how they are kept and how healthy and happy the other chickens are. I also don't know any fool-proof way to tell the boys from the girls, but some types can be sexed by their color when they hatch if the parents are the right type. I prefer not to have a rooster either, but it looks like we have 2. They better be well behaved, as I have a neighbor who would help us make chicken and dumplings ha ha.
Novice advice: They grow very fast! Be ready for that. We were ready to move them into the coop when they were 4 weeks old.
