Less eggs due to heat?

[Big Doggie]

I have 6 hens, I’m only getting 2-3 eggs a day. My one hen is always panting and wings out at night even when the others are fine but she does eat a lot. I have a rooster who is causing feather loss when mating. There’s a lot of stressors and the heat is adding on to it. They are 2 years. How can I cool them down and cause less stress.

I have 6 Golden Comets and was getting 3to 4 eggs a day but in the last few days I’m getting 1 or 2. Today nothing. I guess the heat is a factor.
