Not sure if this the right place for this question but here it is --- how long does one wait after setting up a breeding pen before gathering eggs to make sure the cock bird in the pen is the actual sire? I've been gathering at 5 weeks, but it appears that isn't long enough since there was an oopsy in the last hatch that had to have come from the previous cock bird.
They say to wait at least a month, and after that chances are good they'll all be fathered by the new cock. Five weeks though, wow! Maybe she got out or something and mated with the other boy?
