So my RIR seems to lay a speckled egg every 6 days. I just noticed the pattern today after giving my great aunt a dozen eggs from last week and looking and realizing that the eggs I just grabbed from the nest boxes also included another speckled egg a week later. Is this normal or cause for any concern? What would cause only one out of so many to be speckled? Is she deficient in any nutrients? Or should I just take it as a pretty egg in addition to the others she's producing? TIA!
