Hi Ben and Fi,
Ben - So you think Grey Turquoise Cinnamon too? ( I think I had it backward - Cinnamon Turquoise Grey?- but then I am in WA, and they say we're a bit backward here)
Those Cinnamon WHWT's are gorgeous!! I can only dream of owning/breeding that quality of IRN one day, (if my husband will ever relent and let me! Oh, and if we have the right property/facilities etc etc etc)
Fi - (quote)"I've been reading all these posts about breeding/mutations and have to say Im getting a bit jealous makes me want to get in on the action too!!" (end quote)....... I'm hearing ya! I've become soooo addicted to this site, and to studying the genetics and different mutations of these birds! It's so fascinating! But to quote one of the other breeders, breeding IRN's is a game of patience! If I'm ever lucky enough to be able to get into it on a moderate to large scale though, I'd like to be armed with as much info as possible, and ensure that I make the right choices in breeding stock too

And it's quite possible your bird and the others were from the same parents, if the others were grey/silver and blue......the grey/silver is actually grey cinnamon, and your bird has cinnamon also. Here is a possible combination that could produce all 3 of those colours in chicks;
1.0 grey(sf) blue cinnamon
x 0.1 turquoise(parblue)Blue
% from all 1.0
25.0% 1.0 grey(sf) blue /cinnamon
25.0% 1.0 blue /cinnamon
25.0% 1.0 grey(sf) turquoise(parblue)Blue /cinnamon
25.0% 1.0 turquoise(parblue)Blue /cinnamon
% from all 0.1
25.0% 0.1 grey(sf) blue cinnamon
25.0% 0.1 blue cinnamon
25.0% 0.1 grey(sf) turquoise(parblue)Blue cinnamon ****
25.0% 0.1 turquoise(parblue)Blue cinnamon
Which would mean you have a girl!! But really, that is just surmising....so don't take that as gospel!!

They could have had different parents after all
