I did start keeping a tally of how many eggs I collected each day, but I gave up after a couple of weeks, my OH kept collecting the eggs and then forgetting to put the number down!
Having 20+ chickens (23 and 3 chicks) means I cant keep a tally of who lays each day (they all free range (apart from Darla and her chicks)) so trying to figure out who laid what would take all day.
I do know which ones are ex-batt eggs and which ones are Amberlink eggs though.
But I dont consider you sad or mad for doing it, I keep a note of when my chickens and ponies were wormed, visited the vet etc etc. It all helps when things go wrong
