I see that you have plenty of interesting items inside.. Those are spots that chickens would just hop onto. You seen yourself that in just short time,, the great flood diminished,,,,, to just a mini one.What would've happened if I had chickens there? Would they have been miserable? Worse?
It may be a good idea to place a tarp portion over a section of hoop that is waterproof. The shade-cloth does minimize the rain effect, but a small tarp in adjacent spot would make that area rain-free. Chicken will seek out spot where it is not raining on them.

Earlier post ,you had a concern;; "what to do if chickens are fighting"
You got good advice already, As long as there is no serious injury,,,,,, that is how chickens live. and sort things out.
I just wanted to add this little trick that does teach chickens some behavior adjustments,,, without hurting them.
If you have a water hose handy, or even better,,, a Squirt gun. Yes,, the kind for children playing.

Worth a try. I have used the squirt gun method on my flock,, when I want them to get out of a certain area of my garden,, or such.
