Cochin Thread!!!

so call her calico. LOL  all of my mfc have partridge in them too...  my 2 primary hens are blue partridge split for mottled. put with a mfc roo, I get MOSTLY mfc chicks. either way they are very attractive.

Thanks. I was quite surprised to see it, as the chances were only 1/64 according to Henk, and I got one out of two eggs. mottling seems to work well on partridge though. Now I need to get Pg pure in my girls so I can see some better pencilling.

Quote: actually, getting motted AND PG/PG might give you that ratio, but out of 2 partridge split mottled, you've got 25% of getting a mottled chick. regardless of what other genes it carries.

henk's chicken calculator is ok, but if you don't know the ENTIRE background of a bird, then you are likely to miss something somewhere and end up with surprises.

that's why I hate when people say 'if I breed a black to a white what will I get?" the truest answer is, 'don't know'. because so many other mutations can hide as either heterozygous recessives or totally masked by others... like white. it can hide any number of other mutations, both solid and pattern types, enhancing or restricting red or black pigments, etc. since the white removes all pigments, you can't tell when you have a white on white pattern, or a eumelanin enhancer or pheomelanin restrictor, or, god forbid, ALL of them. LOL

not too likely but it would be possible to have a white carrying lacing, barring AND mottling, with mahogany and the dilute gene plus Columbian and the melanizing gene... and you'd still have just a white bird. black can hide many of the genes as well, but not so much the ones that affect the patterns, like mottled and barred. since those genes remove pigment at certain periods during feather growth.

ok I've rambled enough for today...

Thanks as always Ki4Got, i think Henk was referring to moving mottled onto an e^b base, the linkage there being loose (1/12).

I hear you on the "if i breed this to this what do i get", i saw such massive variances in mine, with strange birchen and mottling popping up, so you dont know what will come out unless you know the history.

I think the other important thing that people are forgetting is, what the parents were(if they know) and you should also indicate which bird in the cross is male.

i did test breed and cull all but one from last season (we are in winter here) i know know that i have 3 birds split for mottling, and my black birds are carrying some silver somewhere (havent narrowed that down yet). I also now know my partridge are both Pg/pg+ and Mo/mo, i also know they have no melanotic or mahogany. Next season, it will be figuring out what my whites are made up of (really hoping dominant white)


Really fun stuff. Glad you got me into genetics, i am loving it.

Hi Craig, it is great seeing people working on the patterned birds. how are you finding the type on your GL so far?

From my reading people are saying they cull for overall pattern after the first true moult, i can see why that would discourage people working on them, having to wait so long to see how the lacing will turn out.

Not really specifically Cochin related, but I would love to learn more about genetics. Can anyone direct me to any poultry genetic books for beginners in genetics?
Thanks for any help

I think type is certainly acceptable for a Cochin. Not nearly as typey as a Black but for their age there is adequate width and cushion. I think I will know which birds will not make it after molts and those will probably be culled unless they are loaded with type. The rest will just be wait and see. I love the challenge of a patterned bird but sometimes have to remind myself just how slowly they develop.

Quote: typically, partridge and mahogany go hand in hand... without the mahogany, the partridge just looks washed out. look at your calico girl. if she didn't have it, she'd be more golden colored than she is.

ours are like the British pekins, I only really see the difference when I look at the partridge rocks here, they look like your partridge wyandottes. Beautiful rich red. Our rocks look better then our rhode islands here too and all I have seen are pure for Pg. I wish or cochin people would take some notes from our partridge rock breeders.
