I've got a (hybrid) hen that ever since she started laying actually gets earlier each day, meaning she carries on laying all through the night until it's gets back to daylight hours again.
This would obviously mean that at some stage she would have to lay 2 eggs in a day, but due to numerous reasons I've never been able to confirm this before today, due to all the hens currently being layers, the nest boxes being cleaned out, and having one more egg than hens.
Is this that unusual? I've was worried she was going to wear herself out, but she just keeps on laying, never missing a day.
