Is it still raining?
can they spend the nights in the jaccuzi and the days in a dog pen?
Do you know anyone who has an xpen? I have one that is 4 ft sq and has a wire lid.
it's hard to know your options not knowing if you have a garage, covered patio, etc.
it's pretty easy to make a temporary 'yard' for them for the days with deer posts and chicken wire. you might want to cover it as well
then just scoop them up and put them back in the jaccuzi at night so they are safe from predators
Oh, I've used 2 wardrobe boxes taped together (from uhaul) on their sides with pine shavings in the bottom and wire over the top inside as a brooder box. I've had chickens in there for up to full size while they were waiting for their 'home' to be ready.
wild weather, good luck
