Calcium coated eggs and soft shelled eggs

[DarlingFarmGirl]

My French Blue Copper Maran began laying back in May. All of May and June, she laid beautiful eggs, probably about 5 times a week. All of July however, she has begun laying an egg for consumption or incubation, only about once a week. The others are either calcium coated or soft shelled, and are typically laid on the same day, and outside of the laying box. I'll find them in the coop on the floor in the morning.

My question is, is this possibly due to the heat or perhaps she needs a deworming? Or does she have a defective shell gland? If it's a defective gland, would she have laid "'normal" eggs for 2 months? Would she continue to lay a normal egg on occasion?

Stress of any sort will impact egg production. Heat on the list there. Consider the diet; balanced or not? Then unfortunately chickens do develop many health problems, and I hope she's not ill. Mary
