strange laying hen

Anyone had a hen which lays 4 eggs, or 2 hens that pair up, both lay 2 eggs which are fertile, its a funny one  

no cocks in what so ever paul,have you let them out ect ect,there loads of things which could happen to make them lay fertile eggs

IVE HAD 2 HENS PAIRED THIS YEAR AND EVERY ROUND WAS 4 EGGS, NONE OF THEM HATCHED BECAUSE TRHEY WERNT IN CONTACT WITH ANY COCKS, NOR DID THEY FLY OUT OF THE LOFT......yours must have been in contact with a cock paul in the loft, or been out exercising and a cocks tread them......JMO

yous are probably right, its just thats its happened again when after raising a healthy young un, 4 eggs appeared in the same bowl again, must have been tread by another cock, strange though never had that before.

but again why do the 4 eggs appear at the same time every round:confused:

I have had a couple of hens that lay 3 eggs and they all hatch and they are  paired in closed boxes with their mates until eggs are layed. But obviously hens cannot lay fertile eggs so one way or another the hens have come into contact with a cock bird. Maybe you have a Butch hen that is really a  Mincing cock in with them.
