Ok-- getting many differing opinions on this one... Please help me out... 1st, let me clarify that I am referring to the fertility of a Mated Hen--not the e g g s from that hen... HOW LONG after she has been with a Roo, do her e g g s become "unfertilized" again? I need to know how often I need to send the gals to "the Love Shack"!!! We were taught in biology class (a LONG time ago) that the sperms viability lasted only 3 days... which is what most folks I've asked have said as well--- But others are telling me 3-4 WEEKS!! I am SOOOO confused!!!!!
