Here is the pic of my leghorn pullet. It finally arrived from my phone....don't know why it took so long.
This is from a closed flock that I have never seen a stub in during at least 30 years of breeding these. I culled the parents and the offspring...don't know how this happened, but all my pens have tops on them and other than the leg feathering, this was a good looking pullet.
To be a serious breeder you have to insure that there are no "mistakes". No male should be somewhere it should not be.

I might not have culled the parents without further breeding of them to see if it happened again
but I applaud you for doing so.
Most accept many theories as facts, and in chicken genetics any breeding results that fail to support a widely accepted theory are often either explained away by a mistake as to who a parent was, or a mutation. I believe it's possible that many so called mutations that occur at a relative frequency [frizzle feathers and feathered legs come to mind in birds] are a result of a so called dominate gene carried by some, possibly even most or all members of that species or family, that are normally accompanied by a gene that serves as an off-switch to keep the dominate gene from being expressed. If the suppressing gene is lost or damaged in the exchange of DNA, the so called dominate gene is expressed and it's then claimed a new gene has appeared.
I wouldn't be very surprized by a feather legged chick appearing in a line that expressed down between the toes; nor a frizzled chick appearing from a line that expressed an occassional curled or twisted feather.............................. which is why I'm so prejudiced against pulling those feathers for show or sale, or breeding them and selling their offspring to an unsuspecting person.
I agree with your post......Like the switch notion too....sounds very possible. I'm just saying to the folks here......don't believe everything you read. Geneticists don't always agree either, another clue that it is not precise when applied to chickens.
If we knew what was really in these chickens we could use most of the genetic rules. If I only had a few birds I couldn't be this ruthless in culling, but I have a 100 or so I can be heavy handed. That was a male mating that produced some very good males, but I have two more others that are about the same..I just have to be ruthless in culling. It has always payed off in the long run.
