Does anyone know what Isa Brown x Plymouth Rock chickens look like?

Hey Mountain Peeps I talked to you yesterday re the article contest. I think I am going to write an editorial on the chicken project they have here in British Columbia through some small non profit society I think based out of University of British Columbia. They have been breeding and releasing chickens in this one forest grove on The Sunshine Coast. I am going to try and interview one of the scientists involved with the project. I also was talking with a woman at the store (how I found out about this strange project) and she was saying that there have been plenty of sightings in this one town called Roberts Creek flocks of feral chicken coming up the ravine onto peoples property getting into the trash etc. Might be interesting. I hope to catch a glimpse of one and snap a shot!

Well thank you for the warm welcome I also roll with JC ;-)

I just hatched 3 PBR over ISA Brown and wouldnt ya know they turned out like these EXACT. One of the yellow ones died in the brooder not sure why he was struggling since he stepped out of his egg. Just for kicks what did the sexes turn out as?

One of our yellows struggled shortly after he hatched, lost his feathers but thankfully recovered, stripes are girls, yellows are boys...

Welcome to BYC! Glad you decided to join our flock. Your chicks turned out beautifully. The black ones with the white spots on their heads look just like Barred Rock chicks. Please feel free to ask any other questions you may have. We are here to help in any way we can. Good luck with your chicks.

Thanks bro I appreciate that. Say listen can you tell me what is the rule for passing genes for example does the mother pass on her genes onto her sons and the Roosters pass theres onto the daughters ? Is there any method to this? I am slowly deconstructing the ISA Brown mystery apart from the obvious RIRxRIW. Everytime I cross back I am shocked at what was staring me right in the face in the first place with regards to how different the ISA Browns are among each other with different traits. My F1s are quite vigorous they dont lay around much. Wish I could say that about the hens lol Thanks again for the warm welcome feels good to be welcomed

can you tell me what is the rule for passing genes

I'm not a genetic expert by any stretch of the imagination, but here is the gist of it. There are two commercial varieties of sex link chickens, the Black Sex Link and the Red Sex Link. In the Black Sex Link, the red gene works with the barred gene, and you get black females displaying red in the hackle feathers because crossing the red rooster with the barred hen cancels out the only barring gene in the female and takes the double barred male down to one barring gene so that the male Black Sex Link is barred. In the Red Sex Link, the dominant silver gene works on the red gene so that the dominant silver gene wins out in the male birds and displays a mostly silver (whitish) male bird with red flecking and an all red female with silver (whitish) underfluff. One of the interesting quirks of these sex link hybrids is that these particular crosses increase the egg production in both sex link varieties over the parent breeds. In the commercial Black Sex Links, Rhode Island Red roosters and Barred Rock hens are the breeds usually used in the crosses, and in addition to the label, Black Sex Link, a few hatcheries also market them as Black Star or Bovans Nera. The Black Sex Link chicks can be sexed by color at hatching (male chicks are black with a white spot on top of their heads, female chicks are solid black). In the commercial Red Sex Links, either Rhode Island Red, Production Red, or New Hampshire Red roosters (all red gene males) are crossed with White Rocks, Rhode Island Whites, Silver Laced Wyandottes, Delawares, or Light Sussex hens (all silver gene females). Various hatcheries market these Red Sex Links under a lot of different labels, including Isa Brown, Red Star, Brown Sex Link, Gold Sex Link, Cinnamon Queen, Bovans Brown, Golden Buff, Golden Comet, Hubbard Golden Comet, Shaver Brown, Babcock Brown, Warrens, Hylines, Gold Lines, Lohmans, Lohmans Brown, etc. Like the Black Sex Links, the Red Sex Links can also be sexed by color at hatching (male chicks are silver or whitish, female chicks are reddish). Both Black Sex Links and Red Sex Links, no matter what label under which they are marketed, are egg laying machines.

So in theory anyone of these barred chicks that turn out female will be useful as a sexlink if i cross them to either a the rooster or black type rooster? The faint barred gene will be passed to the sons?

I have a barred rock rooster and ISA Brown hens and I'm hatching them out with Silkies hens right now. The first baby to hatch was yellow. Does that mean it's a roo?
