Congrats on your new babies @WVduckchick !OK, thanks for the advice. I'll wrap the kennel with hardware cloth and try to get the plastic tub under her tomorrow, and then tomorrow night in the dark I'll try transferring her. I'll let her know how it goes! Thanks for the advice!
On my end, I decided it makes more sense to build a better brooder box than wrap that kennel in hardware cloth. And at the same time, the curtains around the nesting box where my broody is laying seems to have helped with the kerfluffles in the nesting boxes, at least temporarily. So long story short, I did not try to move my broody last night. We'll see how fast I can get the new brooder box built; I may still transfer her before they hatch, and if not I'll wait till after. Thanks for your help again @PD-Riverman
