Coulda been any early layer, might have been a hiccup egg, an inquisitive peck or an accidental breakage... if eggs break, they will gobble them down fast... might try sticking golf balls in the boxes, it helps sometimes to show 'safe place to lay'... although I had 6 boxes in one coop and 7 hens would line up all the way down the ramp waiting to take their turn... if they get a favorite box/place, that is the spot, lol...
Btw, was gonna mention be careful using hay in the coop... straw is better if possible... hay has moisture still in it and can mold in spots... I ended up with a coop of chooks last year that got Aspergilliosis from hay... :/
I haven't been able to find straw yet? I will keep looking. It is a mixture of hay and pine shavings. I keep the bale in my green house, do it is very dried out. But I will double check thanks for the heads up.
