My leghorn decided to start laying last night but I didn't find it until this morning so it was froze. But then she disappeared for a little bit right after I opened the coop this morning so I went looking and she laid another one but this one was half soft half hard shell. It was only about 12-13 hours in between. Is this common when they start laying again? I'm hoping she's just going to lay in the mornings and it was an oops egg. She's about 4 years old I want to say? I'm not for sure since she was given to me.
