Thank you for replying!They are both red sexlinks, so kind of yes. But they also use different 'formulas' to get to the finished product, so kind of no.
Both should be a reddish color with white undertones. I've seen some relatively pale ones that could pass as buff, not sure about cream. Technically, though, they're a mixed color crossing.
Wow, okay. I think I got it. Thank you very much for that explanation!Thought maybe I should expand on my post a bit because I kinda didn't explain, well, anything.
Neither ISA browns nor red stars are a breed; those are just catchy names that hatcheries come up with for purposefully-bred essentially mixed breed chickens. In this case, both were bred for high egg-laying and to be able to be sexed at hatch. The pullets are red, hence red sexlink; the color red is linked to the female sex. These are created when you breed a red or gold male with the right genetics to a silver or silver-based female. The father could be anything from a Rhode Island Red to a New Hampshire to even a Gold-laced Wyandotte, and the mothers could be a number of things including Delawares, Light Sussex, Silver-laced Wyandottes, silver-based White Leghorns, etc. This is what I mean when I say ISAs and red stars are kind of the same thing, but kind of not. They could have completely different parent breeds, but turn out similar in appearance because of how those genetics work. Some big names even have parent generations that are, themselves, not a specific breed, but also a hybrid like their offspring will be, bred for a high yield of eggs. The only common factor in the parent generation is that they have the correct genes to produce sexlinked offspring so that males and females are distinct at hatch.
Something worth noting, because people often try to do this, is that the genes in red sexlinks, themselves, are incorrect for producing more red sexlinks. If you cross male and female red sexlinks, you get a big ol concoction of different genetics that is not sexable at hatch like their parents were. A true breed, when crossing a male and female of the same variety, will reliably produce offspring similar to their parents. This is also why I say that they technically are mixed-color rather than Buff or Red or Cream specifically. They can be reddish or buffish in appearance, but not genetically those colors. Crossing them with a pure Red or Buff colored bird will not make offspring that are true to either color.
What do you mean they get messed up in feed stores?Which explains why they get so messed up in feed stores.
Genetically, no. Buff is diluted Red (diluted with the gene denoted as Di), whereas cream, as in Cream Light Brown, is a cream diluter (denoted ig if I remember correctly), two completely separate genes. Technically, red sexlinks are neither, though they can look similar.Yeah, I have a Red Star hen and she's kinda pale in color. Pretty close to buff. Buff and cream is the same thing, right?
They are all red sexlinks, so one could make the claim that they're all the same thing, but each is a name for a specific formula of parent breeds that a hatchery has developed. For example, ISA browns were developed by the Institut de Sélection Animale in France (hence ISA brown; Institut de Sélection Animale). I believe their parent stock are two hybrid 'mother' and 'father' lines rather than two specific breeds. They are one of the most prolific red sexlink hybrids out there and so many hatcheries have just purchased parent stock to sell ISA browns out of rather than develop their own red sexlink hybrid. This is why ISA browns are one of the more common red sexlinks out there, but technically speaking, if the parent stock isn't from the ISA, they are not really ISA browns.Yes, they are actually the same.. I read that The Red Star is also called the ISA Brown and they are both the same. They are the best brown egg layers also..
This was my experience with them as well, and why I don't get them anymore. Sweet, personable birds, but they just don't have longevity. I think I only had one or two that beat three years of age, and all of them that died at three had complications due to their high egg production.The problem is they only live two or three years before they start having laying problems. Mine made it to three years old but she showed signs of trouble at two.
All of that is true. But it's not just the Red Stars most others bred for high production also experience problems early in life and succumb.This was my experience with them as well, and why I don't get them anymore.

Oh, okay. Thank you!Genetically, no. Buff is diluted Red (diluted with the gene denoted as Di), whereas cream, as in Cream Light Brown, is a cream diluter (denoted ig if I remember correctly), two completely separate genes. Technically, red sexlinks are neither, though they can look similar.
For sure, I also lost at least one hatchery Rhode Island Red and a Barred Rock to issues related to egg laying. It just seems so consistent with red sexlinks particularly.All of that is true.

Man messing around with nature.
Oh, haha, well I'm glad I could contribute well! I have a lot of base knowledge about red sexlinks particularly from researching and writing about them for another poultry site a few years back. 😄
