Very Stubborn Broodies!

I have two broody hens, a Splash Laced Red Wyandotte and Lavender Ameraucana that are a little over a year old. They have been broody for about 6 weeks and despite my best efforts, I haven’t been able to break them. They are broody buddies and share a nesting box, and seem very bonded (you can barely see Hazel in the picture because Dorothy is on top of her 😂). I’ve been pulling them out of the nesting box twice a day and dunking their lower half in water. I put them in our grow out pen in our run that we use for chicks which has 6 ft chain link fencing around it and a roof, but there is a 10” gap between the top of the fencing and the roof, so they broke out of there almost immediately. Next I put them in my dog’s crate inside the run for 3 days, and this morning I let them out and they went straight back to the nesting box. Can I just let them be broody if I continue to pull them out twice a day and offer food / water? Will they come out of this on their own? I am at a loss and would love some suggestions!
