If y'all are just cleaning twice a week no wonder you're ticked off. If I waited till every third day I would have to use a shovel instead of the cat litter pooper scooper. That much poop would probably break the handle. And if I interpreted your statement right, it's "caking" and not drying. If you wait that long it won't dry as you expect. There is a good bit of moisture in chicken poop and really needs to be spread out to dry. You're letting it pile up and cake. That just might cause dampness down to about 2 inches in three days.
If your husband just "won't" clean every morning as compared to "can't" then you have a different problem there. I would say he probably shouldn't be the one doing the cleaning. If no one else can clean and he's stuck with it then he most likely is just being stubborn and shouldn't have the chickens to start with. We all know the responsibility with owning any animal can be major, and chickens are no different.
What you probably should is get the shavings and replace the sand so he can just mix it up and leave all in the coop to dry. It sounds like that is more to his likings. That way cleaning the coop just once a year and would make him happy.
After all, if we can't have a pleasurable and happy association with our chickens, what are we doing all this for?
I have yet to be discourged with owning chickens. Shoot, I've even changed my life style to fit in with the things I preceive to be "my responsibility" to the chickens. I did the same with Morgan, my dog, and will with any other animal I get. That's just me.
I really hope y'all get it figured out to suit you.
