Okay, honestly, this is where it gets sticky and thin with me. Naturally, all tufted birds have one tufted allele, as having two is lethal - They die in the shell. However, the the size, balance, or symmetry of the tufts and genetic hereditaries of such traits, I'm really not so sure of. I've heard from ONE breeder who told me there should be no worry of having parents with one big, one small tuft or two small tufts, they'll still pass good tufts. However, I'm still curious of the validity on that. One thing I do know is that if you have a bird with both small tufts, YES, they pass on big, good tufts.
For example - The parents to all my Blue/Splash Cuckoo Araucanas were clean faced, with a beautifully but unbalanced tufted cock over them. The offspring, what I have, are varied, but none are good. One has only one tuft that points down, another has a small tuft and big tuft, unbalanced, and the third has both large tufts, but one points straight down, and the other is quite horizontal. So that makes me wonder - Is the balance/angle of the tufts a genetic trait? I'm not sure yet, but will find out in the spring.
Another example - My Lemon Blue cockerel has one small tuft, one large tuft. The only offspring he's given me so far with tufts either end up with one small tuft one big tuft or only one tuft. Again, I'm wondering if I'm just getting bad odds or if the lack of symmetry is genetic.
I'd love to hear from others' experience though! I know a lot of you out there have very nicely tufted birds, but anyone worked with birds that have unsymmetrical tufts? (different sizes, different angles, or only one tuft)
And of course another thing I'd love to know is if a tufted bird really does pass on its symmetry, does a clean faced bird ever decide the fate of the tufted offspring? Is there anything on the clean faced birds' face that could destroy or better the tufted bird's symmetry?
