Ok needing some pros advice... I have a broody who is a stubbon mule (so to speak) she has been isolation for at least 36 hours dunked in a tub of water and still is not broken. So my question is there something else I should try or should I let her have a few eggs? Currently still taking her out of the nest.
36 hrs is nothing, that's just your regular broody, now when you hit a week, then, you can call her stubborn

You can try all sorts of things, lots of weird and wonderful ideas on here

I don't do any more sometimes than leave them in the backyard instead of the run so they can't get into the nest box and even that works fine. It's just about keeping them off 24/7 but 3-5 days is fairly normal.
