Does anyone know if these coops are good? I have 8 chickens and it says on their website that you can buy two and attach them together to create more space for 8+, not sure if this is the one I will want to go with.

Well, it looks pretty good but I don't know the dimensions. Personally I elected to build rather than buy because everything I looked at was either way too expensive or way too small for the number of birds I wanted. Just my opinion but as a general rule I think all pre-fab coops are too small unless you're only raising a very small flock. Building the size coop and run I wanted (8'X8'X7' high coop and 8'X25'X8' high run) wasn't cheap either but the gals are happy and safe, and it's withstood some pretty severe weather so I'm happy too.
Are the birds you're planning to get average size, bantams, or very large like Jersey Giants? Also will they be free ranging during the day or are you planning to attach a run? If attaching a run will it be covered or not? Sorry for all the questions but since you're in MA I know you get a fair amount of precipitation so the birds will be cooped up inside probably a day or two per week on average due to rain unless you have other cover they can sit it out under. If they don't have other cover they'll be inside during inclement weather, and in that case it'd be cramped for more than 2-3 average sized birds I'd think. But if they have other cover outside the coop they can get to, and you're going to attach another coop, then you might be ok. I don't know the cost or if that's a factor but I'm guessing it's at least $400 or so each. So, I guess it all depends on whether or not they can stay dry outside the coop(s). I don't know if you considered building a coop or not but you could build a coop from scratch that's 6'X6' (for a little over 4 square feet per bird) for the same price or maybe even less if you have some materials laying around. The nice thing about building it yourself is you can make exactly what you want/need, and make it much better quality than the prefab stuff. I know building isn't for everyone and your time is certainly valuable so I understand if you didn't want to go that route.One of these coops has the dimensions of 28 x 26 1/5 x 43 and you can add as needed.

Thanks for the info will take that into considerationI bought a prefab coop. Two actually. They were discontinued at our local Rural King. I got them for less than $100 for both. Had I paid anymore for them I would have been very disappointed. They sell for over $300 at Home Depot. They wouldn't be anywhere near that quality. I did a lot of modifying and reinforcing. I also added on a very large run since they can't free range because we have so many hawks. If you have the money I would suggest building. If not then go ahead and get one but with the expectation of having to fix it up.This pic is one like I bought.
