    Theoretical, Science Fiction Question

    3KBs, According to R. D. Crawford, poultry scientist at the University of Saskatchewan, the ideal number to minimize genetic losses and thereby indefinitely sustain a flock is 25 hens (to 50) and 20 (or more) cocks. He proposes that all the hens be kept in a single flock. The cocks are to be...

    Pictures of Possible APA Standard Marans Please...

    Quote: This is incorrect, Ione. There are several breeds/varieties whose standard requires 6 points: Minorcas, Jersey Giants, and Hollands to name three off the top of my head. But I can't agree with you more about stressing other more important attributes when selecting/culling breeding...

    photographing eggs

    Quote: The Ameraucana Breeders Club has an Ameraucana Egg Color Reference Chart: http://ameraucana.org/faq.html#FOUR . Both the seller and buyer would need to have one of these charts, though. The seller could photograph the eggs they have for sale with the chart in the frame. That way any...

    black copper Marans vs. black Marans

    I have a theory that to produce exhibition quality (standard bred) BCMs, they will need to be double mated (keep a pullet breeding line and a cockerel breeding line). Plus, I'm not convinced the standard can be met with a purebred ER (birchen) at all UNLESS there are present unknown melanizers...

    Lamonas?

    Quote: One would hope the reason is that the owners/breeders are restricting sales until they have the birds where they should be according to the standard and also production-wise. If any original Lamona stock exists, then it will be highly inbred and likely requiring select outcross(es) to...

    barred rock vs barred holland

    Quote: Standard bred Barred Hollands have red earlobes, moderately large combs and are only slightly smaller in body size than Rocks with cocks weighing 8 1/2 lbs. and hens 6 1/2. The bird Al describes sounds more like the Production Black with cocks weighing 6 lbs. and hens 4 1/2. All that...

    barred rock vs barred holland

    It will be very difficult to tell the difference between a Barred Rock and a Barred Holland chick, especially when you only have the one chick. Both would be mostly black with a creamy white headspot and underside and have yellow legs. Another breed whose chicks would look very similar is the...

    Foreign Breeds

    Here are a few EU poultry pic sites: http://www.kippengrabbelton.be/engels/ (click on "Breeds parade" button found towards top center of page) http://www.pbase.com/johanops/fancypoultry http://pagesperso-orange.fr/volaillepoultry/franc2.html Then there's the old standby poultry pic site in...

    Splash Leghorns

    Many strains of White Leghorn carry the blue gene (and often the barred gene, too-- sometimes both). Crossing within the same breed (Black Leghorn X White Leghorn) might be advantageous in the long run... Andalusians do (or SHOULD) have a distinctive body type apart from Leghorns. This may be...

    Yellow welsummer chick? PICTURES ADDED

    The yellow chick appears to be wheaten and the brown is probably half wheaten and half wild type. Most likely what you are seeing are genes re-segregating (NOT to be confused with the oft-misused term sport). If the yellow chick was a purebred Delaware or RIW I don't think the egg it hatched...

    Breeds needing preservation - how rare

    This is an interesting topic that, for me, anyway, begets question after question but no easy answers... What breeds are truly rare? Which breeds require or "deserve" preservation? What, exactly, does "preservation" mean? How do you "preserve" a breed that has dwindled down to just a few...

    Welsummer Rooster Pick - Which One?? Pics Included

    Unless cockerel #1 has side sprigs on his comb or some other serious fault we cannot see from the pic, I would pick him--hands down. IMHO it is a mistake to cull a bird over a minor comb flaw when it is superior in type and vigor to the others. Good luck! TC

    Cornish

    Ryu wrote: I always come back to this image for the Standard Cornish: http://www.ansi.okstate.edu/poultry/ I think the image you have in mind of the "perfect" Cornish is more of the British standard for Indian Games, Ryu. Some would say that since the Cornish/Indian Game is an English breed, we...

    Breed Representations in the APA Standards

    Don't sweat the pictures overmuch. Poultry judges are not supposed to take these artist's renditions as examples of perfect specimens, anyway. I quote from the APA SOP: "The written text is the description of the ideal bird." In older editions (I have a 1915 edition) all pics are "half-tone...
