Last weekend we found a suspicious white marble-shaped egg in the chicken coop. It looked a lot like a reptile egg. Our new chickens are pre-teens so they are too young to be laying, so we surmised that one of the girls from the 2nd generation (last Spring) has been having issues. Then today we found this in the coop.
Hopefully the trend continues because this egg is at least oval and twice as big as the egg we discovered last weekend.
