You will find that different weather patterns will affect water/wind movement across your land, too. Also, every change you make above land affects both wind & water movement. I've been in shock over the years at what some "simple changes" caused. We removed a tree line between ours and the neighbor's property - DIDN'T realize how much water that tree line both sucked up and also deflected - until we removed it and had a large amount of rain all at once after having the ground saturated by several smaller, previous storms. Even the new & deeper ditches we'd had dug couldn't handle all the water - & for the first time in 10 years, our front yard, carport w/ steps up into the kitchen & drive way were underwater for hours (part of it for days).
Then on new property - ours was very different for 2018 Hurricanes Florence and Michael as compared to Hurricane Matthew in 2016. During hurricane Matthew - our water table (including our well - which partially silted in and became several feet shallower) shifted. Our "pond" - which has never truly been a pond - actually did fill w/ water but also was a lot shallower due to erosion/run off. But the water it filled with drained much faster this year than the land all around it that was higher! WEIRD. It's been over a week since the last rain storms, but even our sandy pastures are water logged and wet - with standing water everywhere that the soil has gotten amended with pony & chicken manures or worse, where flowing water has shifted that said manure. The guy who was supposed to come over and do some swale & berm work for us never showed up, so that hasn't been done. It would help to spread and slow water as it crosses some areas of our property & would have been able to clear up an area with serious pile of sand from Matthew's 2016 runoff and fill in a large hole that developed in an area that we didn't want it (I've actually been working on those two areas - 1 - 5 gallon bucket at a time... or a Gorilla wagon load at a time).
Not looking forward to this coming "rain event"(s) - many days of rain. Though the forecast looks much better tonight than it did this morning. We, too, have a lot to get done to prepare for all the water. Everything that has doors - has gotten water logged/wet and swollen. Sticking regardless of how fit previous to these storms since August. Have to get several coops/runs better filled with yard debris - have LOTS, just hard work to get it all gathered up and put where we want it... 2 hooped coop - pens (1- 8x8' & 1 - 10x10') were so completely wet as to turn into NASTY, STINKY "quagmires" after the last set of storms that dumped a lot of rain - even though they were originally done in DLM AND held up well during both original Hurricanes is Sept & October. They will both need to be dug out before having more litter added - but with this rain coming and needing to coop some more birds for a bit, at least one of them will be just re-tarped over the flat top, more litter added now and then birds put in it...

Just not sure I want to attempt to remove the flat wire, get it hooped/tarped before all the rain moves in - not sure i'd get it done in time...
As the first set of rain hits, I will probably go ahead and process some of the roosters - fewer birds = less damage to the coop/run pens and our freezer will have a nice addition. Might even have to try my hand at grinding up some chicken (though not sure what that would be used for at the moment) - got a Kitchen Aid meat grinder/sausage stuffer for Christmas.
Coops, storage sheds, barns all change on our property. Both on leased/rented places and even since we moved in here. The neat thing is having the ability to make the changes, so that you can make what you have work more efficiently for you.
Nice little coop you have there!
