Are you getting eggs in the morning and getting these softshell or even shell less eggs below the roost? If they are just starting to lay and they are laying eggs during the day then these are called, excuse the term please not mine, fart eggs. They are working at getting their laying in order and this is very common when they first start to lay. You should perhaps change their feed to flock raiser if you do not have all of your pullets laying eggs, if they are pullets, and offer free choice oyster shell to them. Also, smash up any egg shells you have and feed them back to your chickens.
