I'm really envious of your dirt floor! Would love to have one in my coop as I do deep litter but the lay of our land didn't allow for it. That being said, I'm not envious of your flooding problem. I've had that situation before and it's not fun.
Fix your flooding issue first. We used sandbags against our tractor that was flooding and that is a great beginning as it at least keeps the water out. For a permanent fix you'll probably need to dig a drainage ditch or do something similar. You can get empty sandbags at a store like Home Depot and then buy the sand and fill them yourself.
Once your flooding issue is resolved, my thought would be to next predator proof the coop with an apron of hardware cloth or something similar to prevent predators from digging in. The prettiest coop in the world isn't worth a flat nickle if your birds get eaten.
Finally, I'd go with deep litter as deep litter and dirt floored coops are a marriage made in chicken heaven! Keep adding organic material to what's in there, anything you can get your hands on. Straw, pine shavings, mulch, sawdust, leaves, leaves, did I mention leaves?, shredded paper, peat moss, etc. The crawly critters and microbes in the soil will work with the poo and the litter to create the most beautiful compost you've ever seen. The chickens love it as the deep litter brings bugs from the soil and they get a little snack. There is no odor with property done deep litter and - should you smell something - that's your signal to add more organic matter.
Word of caution - if you go with deep litter, do not get DE - Diatomaceous Earth - anywhere near the coop. The DE will kill the bugs, critters, microbes that are necessary for deep litter to break down and you'll be left with a fetid, stinking mess. Same thing goes for any pesticide. You need and want those critters for Deep Litter to work.
Best of luck with your coop and enjoy your chickens.
Hmmmm. I might have to take some pics later, there is so much fence so close around the coop, especially on the side that is flooding, that I'm not sure about a drainage ditch, I have about 1 -2 feet to work with. Also, the roof slopes to the back side, which is where the flooding occurs. Honestly tho, I wouldnt say it floods bad, just enough to dampen the dirt on the back side. The floor used to be solid packed dirt and I had no problem, but like I said, in the several years I had no chickens, critters like gophers/moles/other diggers really softened the floor back up, that coupled with the rain earlier this year really did me no favors.
The sand bags sound like a good idea tho, and I have a big pallet of old bricks that we laid around the perimeter of the yard when it was built, maybe I could use those and some dirt or sand bags to make a little retaining wall type structure to divert the water around the coop (since the bricks are free, and hey... who doesnt like FREE?! This girl sure does) I really have thought about catching the rain water that runs off the coop roof to use to water the chickens, but havent looked into the laws regarding that here (which, btw, I think is really stupid there are laws against collecting rain water, but that is a whole 'nother rant). The boyfriend talks about it occasionally but that's about as far as we've gotten. I really feel like if i get something started, with the way the dirt washes down the hill towards the coop, it will probably remedy itself in no time as the dirt builds up. Thankfully the little "retaining walls" i have made from railroad ties do channel most of the water around the coop. I think it really is the run off from the roof that causes most of the issue now that I thinkabout it and I guess the easiest cheapest fix for that would be a gutter, but I need it to rain so I can observe lol. Who knows when that will be!
Thank you for clearing up the DE issue, I read where someone said to use it to get rid of mites in deep litter but I definitely don't wanna get rid of the little mini eco system that is going to power my floor lol.
Thanks again everyone for all the feedback and suggestions!! Love this forum and the BYC community yall rock!
