how many standards relate to physical appearance (phenotype) as it relates to health and function, versus aesthetics?
I kind of felt like you, and to be honest, for years my main characteristic was is the bird alive? Laying? enough said.
But I accidentally stumbled on another posters post, and they were discussing what to look for, and I realized that I really did not know much more than symmetry in the beak and wings, and toes. Heavier birds, on the same feed. And if that is all you use it is perfectly fine.
Then I got the great idea, that if I hatched green eggs one year, brown eggs the next, then white eggs, well, I would be able to see when production went down in older chickens. I was quite excited to see my green egg pullets actually produced green eggs this spring.
Then Ted Brown asked "how to chose" and I realized I really didn't know a lot about what chicken should be like. I think the video above, "Build a better chicken' could be applied to all birds and improve a flock over time.
If you just want chickens - don't sweat it, I didn't for years. But if you want to play, to see if you can get something a little better, well come join us.
