ISA-Brown page. :)))))))

i think the thread is an awesome idea. the hens with more white, are they isa's too? i'm just wonderin how much my girls colors will change with age.

An ISA does not turn white with age, of course. You are seeing pictures, on my posts, of breeding ISA Brown to ISA Brown over three generations. The white is very dominant and begins to "cover up" the red in subsequent generations. Yes, These pure white birds are ISA Browns- F3. Chicken genetics are extremely difficult to grasp and complicated, but even these white birds still possess the red gene, it is just that the white is all that is displayed.

 
so cmom, from looking at the chicks from your rir/ riw mix, i wonder if somebody could "counterfit" isa's..... hope that's not an idiotic idea

Anyone can put a Red (Gold) rooster over a silver (white) hen and make red sex links. It's done all the time. They'll look very similar and have good performance, if the right parents were used. But... duplicate, or precisely copy the ISA Brown? No, it isn't possible.

The ISA corporation has bred these Browns for over 30 years. The Four (4) strains used to produce the grandparent and parent stock (the ISA is a four way cross) have been highly selected and refined genetically. Those flocks of grandparent stock are owned by ISA, and the strains are kept as trade secrets. In fact, like most commercial strains, these birds are patented.

Forgive me if i'm misunderstanding this. All i want to know is if somebody could take a red bird and white bird to make something that looks like an ISA. I know there's nothing that can successfully duplicate it. I do not know if anything can visually imitate it. I just think paranoid- like, and worry I don't have the real thing.

Sorry for not emphasizing. I was asking about the birds in cmom's post. Where would be somewhere good to learn past the basics of chickens, specifically breeding, genetics, etc?

Yes it can be done by crossing a Production red male or (RIR,NH,CE) x White Rock, White Leghorn any dominant white female. If you use a black tailed white(silver)female as in columbian patterned, a Delaware, or Silver-laced Wyandotte among others you will create female offspring that will be red/ black tails instead of the red/ white in the tail, white in the wing flight feathers and neck hackles needed to look the part/ or clone of a ISA Brown.

My RIR male cross with my RIW females produced chicks that LOOK like Isa Browns. My RIR male cross with Delaware females produced chicks where the females looked like the RIR father and the male chicks looked like the Delaware mothers.

As stated in the previous post, you can cross a RIR or NHR male with RIW, White Rocks or White Leghorn females and get chicks that LOOK much like the Isa Browns.

? Do you have pictures of these RIW if so I'm sure a lot of folks on here would love to see them as they are very rare item in these days and times.

Yes the big Red roo over Dominant white will produce the clone look-a-like of an ISA brown hen and the male will be more white with red/brown in the pyle zone(wing bows, neck hackles, and saddle feathers) areas
The big Red roo over the Delaware is a typical gold gene/ silver gene sex-link cross & yeilds the exact opposite of the parent gender color pattern to offspring gender color.

Correct, as long as the white breeds mentioned are dominant white not recessive white

The reason I ask this is because Rhode Island Whites are a Rose Comb Breed and the offspring from either a Single Comb Rhode Island Red or a Rose Comb Rhode Island Red over a Rhode Island White would be Rose Comb.



Quote: If you cross a R.I. Red or N.H. with a White Plymouth Rock or a White Leghorn they would not look like a ISA Brown. [at least not the first generation F1 cross]

R.I. Red or N.H. over a White Plymouth Rock F1 offspring would be Black
R.I. Red or N.H. over a White Leghorn F1 offspring would be White

I have both Single Comb and Rose Comb. For my experiment I used my Single Comb females with a RIR male. I bought some eggs and thought they were from Heritage RIR stock but when I hatched them out I could tell they weren't. I used males from that hatch as my male so they are more of a Production RIR. I have Heritage RIR also and they are much darker red almost black color.

Here is a picture.


Here are some of the chicks.
