Frozen comb affect fertility??

.

It's a bit academic for me, as I have already used a frosted combed roo or two with hens. The chicks are cute little fellows, grin. There is no doubt with maiden hens. Most of my birds are pea combed, but I have a few seramas now, single combed in that breed. A few of the mixed race south american ones I have also have a single comb, some say there is passion fowl in them. Single combs sometimes freeze, especially if the bird spent a week in the woods............
I suspect there is some difference in stocks, or that there was a long period of infertility in a particular flock or experimenter's trial group, and that is now accepted as always true. It might be that a bird who has experienced partial organ shut down due to hypothermia is different than a lightly frosted bird...who knows........

I have watched a utube video on retrieving sperm from a rooster, a very interesting method to say the least, they are probably all pretty similar. Artificial inseminating a hen, I have heard a description of it, from someone that worked in the poultry AI industry, very interesting.

By the way, has anyone ever looked at the vent of a hen when it is touched? Smiling that big smile. If you want to see something funny, do that thing, you'll see EXACTLY what I am speaking about. It looks like a little mouth chewing gum . The first time that I saw that (don't ask why I was touching the vent area), I almost died laughing, until I realized what the (is the actual cloaca that is the vent opening, not sure on that) is actual doing, good reason for it to look like a couple of gum chewing lips....rats, digressing here, didn't mean to be rude, or disturb this thread or others, smiling the big smile again, beautiful days, CynthiaM.

I have read those articles on rose comb fertility in roosters, a very good read, read them a very long time ago when someone mentioned to me that the single combed roosters were far more attractive to hens than those with the rose comb, hee, hee.
