One of my hens lays eggs with a wrinkly end. She's been laying since august and maybe skipped 8 days so far and has a red comb. Her eggs are usually a little weird at the end but I read that wrinkles across the middle might mean she's sick. She was laying more perfect eggs for a few weeks but her egg size jumped to jumbo recently and the wrinkles are back. Are eggs like these normal and from a healthy chicken? ETA: the egg is wet in the second pic because I was tapping the end and it cracked a little.
