Like most livestock or pure breeds of animal, they are frequent sold according to a level of criteria they meet, and in this respect chickens are no different.
Show Quality Stock
By definition, an example of a breed that is deemed as being of show or exhibition quality is a bird that exhibits all the visual appearances required for the standard of that particular breed and plumage type that, at the right time of year, and when prepared for an exhibition, would stand a chance of being placed and receiving a rosette. The key points here are “visual appearance” and “standards”. Show quality birds meet the requirements of the show bench, even if they do not necessarily meet the original requirements or intentions in the development of the breed. For example, an Orpington was originally an excellent laying bird with good table qualities. It is now predominantly a profusely feathered ornament, whose utility value has long since been lost in the drive for excellence on the show bench.
This is a point worth bearing in mind when setting out to purchase a pure breed, as show quality birds may serve you well in a show but not in the kitchen.
Breeder Quality Stock
This is stock that will have some defect within its features that would prohibit it from taking any honours at a show, but does have the genetic makeup and potential to be used to breed a showing winning bird. It is a common misconception that two show winners, when bred together, will automatically produce many more show winners. They don’t, and, in fact, they rarely will.
Pet Quality Stock
There is nothing wrong with this level of quality if all you are looking for are chickens that provide a bit of interaction and perhaps lay a few eggs into the deal along the way. Usually, these are pure breed chickens that are sub-show-standard, and shouldn’t be used as part of a pure breed breeding programme. It doesn’t make them any less of a chicken, but it also doesn’t mean they are necessarily pet-like in their behaviour, or docile in their temperament. You still need to make sure you select the right sort of breed if that is what you are looking for from your stock.
This is almost synonymous with the term ‘dual purpose’, as it refers to chickens that will serve the keeper well both in terms of eggs and meat. It is worth mentioning here as ‘utility’ is a function that is increasingly becoming recognised within the show circuit. The Sussex breed, for example, enjoys a buoyant show presence when plumage etc., are judged, but increasingly,the utility value of the bird is being considered and favoured above its look. If purchasing pure breed chickens with their practical livestock aspects in mind, as opposed to showing, then seeking out a good utility line is important (just as looking for good layer or table lines are, if those are the requirements you have). There is many a show winning Leghorn, a breed renown for laying huge numbers of eggs, that has had that characteristic lost through breeding purely for show qualities .
