Brooding Pens?

2 of my Cochin hens seem to have gone broody. Lately, everytime i go to the coop i see my little blue cochin/silkie X setting in the box. My partridge hen has also been growlign and setting. Currently theres only wooden eggs in there since ive been gathering them all.

I KNOW i will not be able to 'stop' the partridge hen from being broody, the machine sat on 8 nests last year. This is the very first year for the blue hen though, she seems very determined too.

it's been freezing off & on lately and is pretty wet. I am just worried about the chicks. Will the hens do okay if i take them away after they hatch & fluff?

I don't have a problem brooding them for a week until they find homes, just dont wanna tear the hens hearts out, lol.

does anyone have experience with a brooding pen? does it work well? they would both go in together for company of course.
