I have 4 EE hens that recently started laying. All is going well except 5 or 6 days ago I found an egg right under the roost and the others have been laying in the boxes. It was still in tact and rough to the tough like my other ladies had on their first egg. Day 2 I found another, smooth and normal, egg under the roost broke. Couple of days later I found another egg with a semi-soft shell on top of the boxes. Today I found a really soft egg under the roost again. Now some of the ones I found under the roost I found around 7 am so I assume she may have laid them while roosting but I cannot be sure. None were eaten just broken like they fell or in the case of the soft one when she laid it. There are 15 in the pen with 2 roosters. 3 weeks ago we moved them to a covered pen that is HUGE. They were more exposed to the cold so we wrapped it in plastic and made sure to leave a little open at the top for ventilation. The sides are 25 - 30 foot high. They eat Layena Layer (not sure %) with scratch in the a.m. to warm them up. They also have free access to oyster shell and free-range over 7 acres. Will this issue work itself out or should I be worried? Thanks!
