Hello, First time post, long time reader haha. I have a 4x6 coop with attached 12'run with 6 chickens and 2 Ducks. I'm going into my first winter and have been trying to figure out my approach. My coop was loosely designed off of what I found on this website and what was available to us. It has worked well this summer but being in Michigan... Well... Winter is coming! I like the idea of the deep litter method, and have been adding wood shavings and tossing the coop every day or so with a shovel to mix in droppings. The chickens don't lay in our nesting box, which is an issue in itself, even though the roosting bars are well above. I think the fact that I have two ducks who night sleep in the boxes at night have something to do with that. They kick out the wood shavings even when I had a little wood ledge there every day so I've given up. Anyway, I can open up my back coop doors and smell some ammonia smell. From what I read, I need more ventilation. We have a big 1'x3' window on the high side of the coop, the pop door, and tons of holes drilled with hardware cloth. I'm thinking we need to drill more holes on the outside wall where the doors open wide for cleaning, but am worried as it is exposed to the outside with no overhang or protection from rain getting in. Also, is deep litter with wood shavings not a good idea for winter? Should I go to sand and a poop hammock for winter instead? I figured the thick layer of wood shavings on the bottom floor of the coop would give a nice thick insulation cushion for them. Please look at my coop pictures and give me input on the design, ventilation options, and how to prep for winter. I am thinking for the run putting plastic sheeting up so they have a nice sheltered out of the wind exercise yard with a heated dog bowl. The ducks make short work of water in the bowl though playing with it. Love the littler buggers though! I'm not sure what I should put in the run for winte,as I have been using pine needles which have worked great but I'm running out. Also I won't be able to rake them up when the snow is down anyway. Straw? Same wood shavings as the inside of the coop? Just concerned about wetness from the ducks mixing with the chickens causing bad health. Thanks.
