In addition to the scientific literature available, I ran a research project on that myself. I used a group of hens with recessive white color and artificially inseminated them with semen collected first from a Dominant white male, then a brown, then a dominant black male on successive days with semen from the black male inseminated on the third day. Gathered all the eggs and labeled them by date laid and set them. Wouldn't you know, the first eggs laid hatched black chicks, then several days later we started getting some brown chicks mixed in with the black chicks before they eventually were all brown and then after about 10 days we started getting a few white chicks mixed with some brown chicks and no black chicks with nearly all the last chicks hatched being white.

Isn't chicken research fun!!!!

yep, sure is.

I found it out in a similar way, just from roo swapping from pen to pen. I'd set every egg regardless, but labled them just like you on a roo change, every time, the 3 rd days eggs were always fertile from the new boy

And that third day egg will become the second day egg if the hen is mated prior to her laying her egg that day. If you change males in the afternoon (after she has laid that day) then the third day is the earliest he can produce chicks because of the presence of an egg in the oviduct at the time of insemination. Sperm can not transport to the site of fertilization until she lays her eggs the next day and it can not get their in time to fertilize that days ovulation which will occur 20 minutes after she lays an egg. Ok, maybe TMI. So in essence, ye, by the third day following insemination (successful mating) ova will be fertilized by the new male.

yep I work til 5-6 or later every day, so my bird work is always in the late evenings, done for the day by then.
I need to add though, this is only the case if you leave the new male with the hen. If you do just a day or two, the old male will come back from sperm storage.

True, however after the stored sperm from the newest male (previously the old male, round number two) is exhausted then the hen will start using sperm from the next most recent male (the new male) to inseminate the hen then it will use sperm from the old male (round number one). It truly is "last sperm in first sperm out" until the tube is exhausted of its reserves. The sperm storage tubule is a dead end fold or crypt with only one entrance so old sperm basically gets buried under layers of the newest sperm deposited.

Just thought I would illustrate the multiple (extra) tail feather pairs that occurs in some longtails. Here is one of my young stags around 10 wks old. He has 24 main tail feathers. That's 12 pairs. It makes his tail fan because it is so full.. Reminds me of a Satsumadori.

That's awesome!!! This is something that can be selected for at a very young age too.

 

[onagadori]

yes it is.. It is quite interesting looking too.. I have been told that according to the research of Brian Reeder, it is a recessive trait that can be selectively bred for.. Brian put out a new book this year about feather genetics.. Should be a good read.

Correction.. last year.. 2011.. lol. sorry

Wow that bird is nice...It has a very nice fan tail on it.....TM
