Quote: Silver is a dominant gene; its alternative allele is gold (there are also others, but they are not common).
Every chicken has some allele of every gene that chickens have. In most cases they have two of each gene; with the sex-linked genes, the girls only have one. If a bird has the same allele on both of the genes, it is homozygous. All its offspring will inherit that allele from it. If there are different alleles on each of the two genes, it is heterozygous, about half its offspring will inherit the one and the other half will inherit the other. For the sex-linked genes, the sons will inherit the gene the mother carries and her daughters will inherit the lack of a gene. Having the ability to have only one copy is hemizygous.
I never use the term silver or gold to refer to a variety; it is ALWAYS to refer to the genes a bird carries. Now if the name of variety includes either the term gold, golden or silver, then I use the full name of the variety: gold laced, silver laced, golden duckwing, etc. I use the term silver partridge only genetically, in the same way I would use the terms gold birchen or chocolate partridge. If I am talking about the variety, I call them grey.
In the first photo, it is missing a toenail, not part of the toe. In the second, I would say that it does have an extra toe as well as brachydactyly. Brachydactyly is shortened toes.
One of the chicks I got from a breeder a week or so ago I picked up yesterday to replace the zip tie that fell off its leg and noticed that its feet were messed up. (My bad for not checking them, but I trusted her word that they were fine). One foot is missing half a toe and the other is missing half a toe too, but it looks like would have had extra toes on that foot if it had grown![]()

Quote: I have seen that before - one of the normal toes doesn't grow a toenail. I hadn't seen one that didn't even grow the toe..
I think it is genetic - but since the 5th toe can be suppressed by temperature fluctuations during incubation I wonder if it can cause this also?
good question

My son's very first show is today. He's so excited that he's awake before sun up! He told me last night that he didn't care if he doesn't win but he just wants to see all the chickens!

Tell him all the people in BYC said GOOD LUCK!
