Proud farmer boy

We have had our silky hens for 3 months and our brown hens for 2 months put record amount is 9 eggs in one day. All
Eggs have been small
Until today da da daaaaaaaaa we have a huge egg been layed probably by a clever brown hen. Ben goes out in the morning after breakfast and opens the Hen house and let's them all put to roam. Then he checks for eggs on and off during the day when he is home usually before and after school and before they all go back in to roost up for the night. He was very surprised today when he came home to see this big huge egg.
