Can you drop in a few pallets and cover with straw??? Tha should allow the water to flow thru and give the birds a moderately dry area to walk.
that's an idea, but i would be surprised if the water hasn't drained out by this afternoon, now that the rain has stopped.
thanks all for the suggestions!
Hens go broody when you don’t want them to… and won’t go broody when you do.
