My mother-in-law gave us keets May 9th, and wasn't sure how old they were, but they were supposed to be "day-olds". Their bodies weren't much bigger than a quarter. They've been mating for about a week now, and today I found an egg in the middle of the field where my husband's Bronco and trailer had been parked yesterday - their favorite place to hide under. Our chickens which were day-olds received April 14th have been laying 8 days now, and all of their eggs have been in the nesting boxes, clean, perfectly shaped, and warm light browns. This egg was cream, dirty looking, and out in the middle of nowhere. Could the guineas be laying this early? We're in west Tennessee, the temps have been mid-eighties, to mid-nineties. This picture shows the egg in question, one of our chicken's first eggs, and a store-bought egg.
