She lays daily, it’s hot right now so all the hens are panting, and usually by the time I catch her, she’s also panting

Maybe I’ll have to sneak a camera up to the roost.
she’s super active, and lays daily. Her eggs are sometimes kind of odd, sometimes they look like they had a crack through them, and was welded together in the middle. Other times her eggs are slightly flattened on one side. She’s always the first to come for food.
Her belly definitely feels somewhat squishier than all of my other birds, Initially I suspected mites and did a round of ivermectin for everyone, but no one else has a balding belly like she does.
