casamber 60 Report post Posted November 19, 2012 Im not very good at sex linked mutations and dont usually breed them, so need a little help.... I have 2 chicks fledged last week. Parents are a CFW cock and grey hen. Both chicks are CFW so i know they are girls, but... One has a black beak with black tear marks and white feathers, the other has a horn coloured beak with fawn tear makes and creamy feathers. So the cock is obviously split for fawn right? But then why are both chicks not the same? I thought that if a a cock was split to a sex linked mutation then it always shows? Obviously thats not case right? Im so confused now...

norfolk flyer 208 Report post Posted November 20, 2012 Kerry, I'll try and keep it simple, all what you said is correct. Now because the male has inherited the fawn gene, he's carrying 2 (cfw and Fawn cfw) both of these are basicly even, so for ex, your 2 young could have quite as easily been 2x cfw or 2x fawn cfw, but yours has produced one of each. It's a difficult one to put into words, if Paul reads this probually he can put it a different and more understanable way, but i hope this has made things a bit clearer.

casamber 60 Report post Posted November 20, 2012 Ok that makes sense. I just assumed that if he was split for fawn he would always produce CFW fawns. So, on a slightly different note... can a CFW produce grey hens? Or just CFW hens? Thanks for the help! Kerry Share this post Link to post Share on other sites
norfolk flyer 208 Report post Posted November 20, 2012 Kerry, Only if the pairing is Grey x CFW = 50% Normal Females 50% Normal/Chestnut flanked white Males If the pairing is the other way around = 50% Chestnut flanked white Females 50% Normal/Chestnut flanked white Males Hope this helps, Trevor Share this post Link to post Share on other sites
casamber 60 Report post Posted November 20, 2012 That helps a lot thanks Trevor Thats what i always thought it to be but am now starting to doubt my knowledge on sex linked mutations! Seems i have more to learn than i thought Kerry Share this post Link to post Share on other sites

Dimitri 1 Report post Posted November 20, 2012 Hi Kerry CFW fawn chicks usually don't have horn coloured beaks, that description looks like a continental cfw hen. If it be so, the cock would be a CFW split CCFW and would be able to produce CFW and CCFW daughters. What about the tail coverts of the creamy chick? Are they washed out like in cfw, or evenly darker than usual? cheers Dimitri Share this post Link to post Share on other sites
paulm 119 Report post Posted November 20, 2012 Hi Dimitri I dont keep CCFW's would a fawn tear mark be found in them as i was of the understanding the CCFW's where much darker marked than Most of our uk CFW's or is this because i see mostly exhibition CCFW's?.

Dimitri 1 Report post Posted November 20, 2012 Hi Paul here is a young grey ccfw, just fledged compared to a regular cfw fledgeling, note the creamy overall colour, brown tear mark, horn coloured beak, the tail coverts are the same colour as the tear mark. After moult the tear marks and tail coverts darken to black or almost black. ciao Dimitri 1 Share this post Link to post Share on other sites
paulm 119 Report post Posted November 21, 2012 Hi Dimitri Thanks for the info there's a big difference between the fledgeling and adult bird in terms of the markings. This young Continental CFW will be much darker in the tail than the uk CFW's once adult plumage is gained and retain a creamy back tint as it has now. Dimitri do you have a adult CCFW shot showing the tail colour as this could be a little confusing for some. Paul. Share this post Link to post Share on other sites

The back is getiing creamier in colour as she gets older. I will try and get a picture soon. Thanks Kerry Share this post Link to post Share on other sites
paulm 119 Report post Posted November 26, 2012 Hi Kerry If you compare the markings and colour on the UK Cfw below you can see the huge difference. Paul. Share this post Link to post Share on other sites
casamber 60 Report post Posted November 27, 2012 Thanks Paul. Her tail markings are much darker than that picture and her back and wings are very cream in colour. I wouldnt mind producing a few more this colour, its very pretty. Kerry Share this post Link to post Share on other sites
