Hi, I'm currently planning my next goose house as my guys are out growing the repurposed chicken coop turned goose house they currently live in. I only keep them in at night. I would love to see pics of other peoples goose houses. I'm thinking concrete or sand flooring. I'm leaning to concrete as I can just hose it to keep things clean, but have done sand in coops and liked it too. Of course chickens seem to poop less. I'm not sure how much more I'd end up digging it out and replacing? For concrete, has any one tried collecting the poopy water run off for liquid fertilizer? If so please share! I have also toyed with the idea of a moveable coop, but they trample the ground so fast I think I'd end up moving it every day to avoid bare spots.
