Ok cs, it looks like your coop pics were taken even before day one minute zero.
So you can't open up that door on the enclosed area, park a wheelbarrow right in front of it & rake it out? Bummer.
Ouch. With a concrete floor, either don't make the roosts very high or try to have deep litter to keep them from injuring their feet. Bumblefoot could occur.
Jim, a poop board under the roosts is awesome. I think the birds crap more over night than they do all day long. Ye gads! It makes cleaning the coop much easier since the majority of the doo is on the boards. Just clean off the boards every few days, then you don't have to clean out the rest of the coop for longer periods of time. This works especially well if you do the deep litter method.
Glad to hear the fertility was a little bit better than expected Bigz.
