When you tear up pedigrees , and start breeding type and color, irreregardless of heredity, it becomes fun, and seccessful, if you have an eye.. The AKC would put me under the jail for my winning Silkies' pedigrees years ago .HOWEVER...... as a long time dog breeder, I know for certain, that until the AKC started testing DNA on stud dogs a few years back, many pure-bred dogs' pedigrees were not worth the powder to blow them up.Those pedigrees were solely dependent on the integrity of the breeders.Genetically this shouldn't really be the case though? Dogs and chickens both have the same number of chromosome pairs. Although I suppose other factors like meat quality, and egg production and such would be taken into account where with dogs obviously not. Of course there's also the chicken's ability to have far more offspring than a dog. One of my best friends is a Pharaoh Hound breeder and this is a discussion we've had multiple times and each of them has their own difficulties. As chickens for instance we don't have to do health checks for eyes, hips or any of that. We don't have a registry and pedigrees so if we have to bring in new blood to fix an issue of some sort we can without as much difficulty. So both are challenging, just in different ways.
