Got a turkey egg last night! This this is *HUGE* especially considering how dinky this little hen is




Hoping the pullets are going to start laying soon, but the silkie is laying gangbusters. Always heard they were terrible layers, but this girl has something to prove, apparently.
@kanina I had a silkie roo with a much bigger single comb earlier this year. Was a huge boy. Especially in the bigger "meat type" silkies (as opposed to "show silkies"), you tend to see big guys and single combs. Single combs are a recessive phenotype, so they don't crop up often in silkies, which have at least one kind of dominant comb and might have up to three in the same bird (rose comb, pea comb and duplex comb) depending on who's breeding them to what standard. With all of those dominant alleles, it takes recessive everything at each of those three gene locations to make one single combed.
Your boy doesn't have to be crossed with anything (and isn't likely to be considering that his color is nice and dark, his white's white, and his feather's are silky). He's just got a recessive comb.
Single combs tend to hide especially well in bird's that have rose comb genes (which includes walnut, the American standard comb for silkies) because homozygous rose comb males have decreased sperm motility and fertility in general. Hence, in mixed flocks, the heterozygous rose/single comb guy will outperform and fertilize more eggs--and you won't be able to tell which is the single comb carrier either. This is why you see a lot of single combs cropping up in rose comb breeds, like Wyandottes.
