My hens are pretty much done with their molt and are getting back to full time laying. But, for the last few months I have noticed really soft shelled eggs that are usually broken. I separated the hens into individual pens and this morning when I went out at 4:30ish 3 of them had a soft shelled egg and a regular egg. They were penned since yesterday morning about the same time so I know they didn't lay yesterday and it was awfully early for today's eggs. They get free choice layer, free choice oyster shell (which they don't eat much of), and scratch (a 12 oz cup twice a day for 17 birds). They also get some leftovers but, I keep it low as not to interfer with their diet. The scratch is cracked corn and Boss with a little bird seed and peanuts mixed in. They also have water with either vitamins and probios (probiotic) or apple cider vinegar depending on the fill-I alternate them. I did have issues with some of the others having wrinkled eggs and quit laying this last spring and ended up processing those. I'm wondering if this is a molting issue or an extention of the problem from this spring. They are hatchery Black and Brown Sex-links. Thank you for any help.
