Odd eggs like these are more common with new layers, because of immature shell gland and their need to work all the "kinks" out of their reproductive system. Though you may occasionally get one from an older, more experienced layer too. Make sure your hens get sufficient calcium in the form of layer feed or oystershell/crushed egg shell, offered free choice in a separate bowl/feeder.
My RIR had a few like this as her first eggs. She should end up with shells after a few days to a week. Puberty... it does crazy stuff to even chickens!
We had a couple of Reds this summer start off slower than molasses in January. Double no shell stuff, dropping from roost, all kinds of things. I upped the calcium and it made no difference at all. Those were simply late bloomers and slow starters and only time made the difference.
A month later now and they lay a perfect egg every day. Time is your best friend.
