I currently keep 13 guineas. The first batch of 27 guinea eggs in the incubator is due 6/18. The second batch of 89 eggs is due 7/3.So how long have you been doing this? Do you have a million guineas running around??
Prior to the change in Internet protocols, there was lots of information on guinea color genetics. Much of it is no longer available. I was also able to have PMs with @PeepsCA before she disappeared from BYC.
Due to an error by the provider of my first guinea hatching eggs, I ended up with guineas that it was possible to know what their actual color genes were. Following the color genetics through my flock has been an interesting experience and in at least one case has dispelled some claims about the the color genes of the Royal Purple guineas.
