Oh okay thanks i was wondering because i was think of trying to breed a sexlink polish

Crele Polish should be autosexing..

You should be able to use a Polish male over a Barred Polish female.

Silverudd came up with the term semi-autosexing and the term is used in the literature. There are several breeds that are semi-autosexing. Not every Rhode Island Red has to be show quality.

I understand that not every Red is show quality but most if not all hatchery "Rhode Island Reds" have a lot of Brown Leghorn bred into them.

I was hoping for a red or chocolate polish cross sexlink

There are two ways to achieve a sexlink

1. Non-barred rooster over barred female - this is what they do for black sex-links, using a RIR or NH male over a barred rock hen

2. Gold/silver based - use a gold (g/g) male over a silver (S/-) female - eg RIR over a columbian Rock or Delaware

so would a golden cuckoo maran over silverlaced polish yeild a sexlink

If the male is g/g gold and the female S/- silver, then yes - this would be based on gold/silver and have nothing to do with barring.

For a barred sexlink, you would need a non-barred b/b male over a barred B/- female. Since cuckoo is barred, you could use a cuckoo maran hen and a non-barred male.

Not to redirect the conversation, but this statement gives pause. Many of us have forgotten that the APA Standard exists as the definition of what makes a breed a breed, and it was done for a few reasons, one of which was to protect from fraudulent misrepresentation in a spirit of "buyer beware". As a community, we have fallen into the habit of calling birds by the name assigned in the catalogue, without considering that the hatchery of origin might be a place of low quality and lazy or divergent selection. If one then takes that stock from these hatcheries and compares it to the SOP, one often, if not usually, finds that the fowl in possession do not conform to the requirements of the breed. So, does every RIR have to be TOP show quality? No. Does it have to be show quality, yes, in the sense that it matches the Standard in the basic traits of first type and second color. If shown, it should be evident to all that via its shape it is a RIR. If it doesn't, then it's not a RIR. It's perhaps a descendent of fowl that once upon a time were RIR, but it is not the product of selection to preserve breed-type.

With enough experience looking at most hatchery dual-purpose birds, i.e. Australorps, Orpingtons, Rocks, Giants, RIR, NH, Dorkings, it becomes evident that if you made them all white and, perhaps, hid the comb, it would be hard to differentiate this from that. However, with Standard-bred birds, if you make them all white and cover up the comb, you will, with a little practice and training, perhaps, know instantly which one is which.

If anyone's interested in auto-sexing birds, jump into Red Dorkings or Silver-Grey Dorkings. There are some great breeders working now to help restore them to Standard qualities, and it's hard to beat a Dorking for quality and all-around barnyard worthiness.

As it is used here, "show quality" means those exceptional birds that are the top of their breed in physical appearance. Perhaps "breeding quality" would better describe the minimum quality we would like to maintain, as it would be impossible to have every individual be in the top percentage of their breed. Some birds have many good characteristics, conform to the breed standard in many ways, and can produce even better birds when bred properly.

Unfortunately neither of these standards include production, which to many of us is just as important as the appearance of the birds. Many lines of birds bred to simple visual standard loose those production qualities, such as egg color, size and number, and carcass quality and grow-out rate.

This is a very common misunderstanding, but a misunderstanding,nonetheless. The Standard does include production, meaning the potential for production as is appropriate to the breed type, but not the selection for production, which is on the shoulders of the breeder. Once proper type is set, then type-appropriate selection for production will lead to type-appropriately high yields. If one starts on the other side, meaning selecting for production before type, one will select one's way into the development of a brand new breed with a whole new type, i.e. hatchery "Orpingtons" or "RIR", which are no longer Orpington or RIRs. For none of these qualities "egg color, size and number, and carcass quality and grow-out rate" is it never necessary to breed away from the Standard for the breed.
