hen 6 months

Hi All Its an urgent situation. Since several weeks one of my.hen was getting puffy like puffer fish if any rooster comes near or behaving touch me not types. I realise that this is a precursor behaviour of being broody. Now she is broody since yesterday,and i am already incubating the eggs...

This morning when I went out to check on my birds and do regular maintenance, I noticed one of my hens “squatting”? Here’s some pictures.
