I think they'll work fine--even more than I need, but I still hope for some replies/comments, etc. I am thinking of using this as a coop for a trio, i.e. one drake and two hens. Note also the large north-facing vents. I have a total of 22 sq. ft. of floor space in here. There will be NO chickens, only Khaki Campbells. No roosts, of course; no indoor feeder, and no nest box--at least not the style you see in the background. This seems ample for a trio of one drake:two hens!!! Here is another view, this time from the opposite door into coop. Here is a pic of the south side of coop (IT IS 5.5 X 4 FT IN SIZE, BTW) I guess I took this to show you the nice size of the vents. Also, the run you see here butted against the coop will NOT be used for the ducks..... You also see two windows below the vents... HERE IS THE OTHER COOP. This one is 6 x 3 (18 sq. ft. floor space). This pic shows the nice size north-facing vents--in pic covered with a plexiglass thing, for chilly night. THIS COOP HAS NO WINDOWS EXCEPT THE AIR VENTS. I don't think ducks coop needs more window than this--would you agree?? Here is the 18 sq. ft. interior of this coop. Again, there will be NO chickens! Finally, here is the south side of the coop, showing the good size vents. You can actually see out the vents on the other side of coop in this photo. OH YES, want to mention that I would like to use this 18 sq. ft. coop ALSO as a coop for a trio of one drake:two hens. I would greatly appreciate your comments, all you experienced duck raisers!! Thank you so much for taking the time!
