My coop was surrounded by over a ft of water this last summer till november due to 75 yr rain! we brought in 10 yds of sand, filled over 60 sand bags to put around the coop and 1 1/2 ft sand in coop to get above water level. we put milk crates to dry land for hens to get out and range, but that stopped when bear and cub showed up about 4 months ago and got 5 hens that day. We got a rescue dog the next day and the poor birds were in coop with time out in afternoons when dog was in till hawk got another. down to 7 and they are now out of water and run is dry. water was never this high except for maybe 75 yrs ago! 3 months after our old dog died last feb, a bob cat came around almost every sunday for dinner, covered run and then the bear. luckily here in fla, I have a large garden, so they get plenty of greens in their large run everyday. I had to go 45 miles to get a pair of boots, everyone around here was out! hope not to have another rainy season like that for another 75 yrs.
At least our water spots go down for a day or more before the next rain most of the year. And during the summer we get a dry period when it is illegal to burn. That is when the mud in the run is all gone.
