the new male started mating from the second day we paired them and on the forth day the female layed could this egg be fertiliezed. if not should i thro

Answer
Hi Ali,

The egg could be fertilized. One way to determine if it is is to sit in a dark room and carefully hold a flashlight behind the egg. If you see blood vessels inside, then the egg is fertilized! If it does not appear to be fertilized, you can throw it out, but I would let them sit on it for a while so the hen can recover before she mates again and forms another egg(s). I hope this helps!

Thanks,
Stacie
