About the thin shells, have you a nasty hen or threatening dogs in the area? Fear causes calcium ion channels to conduct and change behavior - that's why calcium channel blockers produce higher test scores and allow dosed, stressed test animals to complete mazes better, especially in older animals. But they cause the lungs to give off a smell after a few days of use. Point is that scared birds seem to have thinner shells. The calcium is being diverted.
