Help with my abnormal actions please!

[jojochickens]

I have 6 layers 3 months old. They been doing real good up until 5 days ago. It seems to have started when we started having hot and humid temperatures. One of my hens just wants to stay in the laying box. I actually have to lift her off and place her outside so she can stretch her legs. Once she is out she seems to act ok but not eating very much and defenitly not laying. Other hens will lay in the same box so i have to lift her off to get the eggs. Can someone please help me with his.

It sounds like she is broody. (She is trying to hatch her eggs, that is.)
