I have a red sex link that's been laying for the past couple months....she laid a hard shell double yolker this morning and then dropped two soft shell eggs back to back in the evening out in the run as we watched. We only have two laying right now and got our normal two eggs this morning so we know she laid one. What could be causing this? Maybe because she's still young and it's her system? This is the second time this happened and I actually thought it was another pullet starting to lay until she was seen laying them.
