I have also seen great offspring come from less than ideal-looking parent stock -- but the parent stock was from a good breeder. I have also seen less than ideal offspring come from some great looking parent stock. This is not a perfect science.
Erin~ I can not believe what some of these people have said to tell you the truth. I keep my chickens as pets that I can carry around and pet and ENJOY. I breed to make pretty healthy birds. I would not cull unless one of my birds was unhealthy. Why does it really matter if they meet some standard if they are perfect to you? Come on guys, try to enjoy chickens for how funny they are, how friendly, etc. When you get sooo worried about standards, I truly believe you forget the whole point. Enjoy your birds and keep them healthy.
Your point of view is fine for your purpose. It all depends on your purpose for keeping chickens. These are multiple. If you keep simply for pets and to enjoy that aspect, then I agree with you, they are all great (there are no bad chickens). However, if your purpose is to improve a breed or to be a keeper of one of these heritage breeds (i.e. a preservationist), or to show a breed (all these reasons are enjoyable too), then you must breed to standard of perfection and take care of business.
A lot of the problems or disagreements that erupt on this forum is due to the fact that people are keeping chickens for many different reasons. I keep mine for many reasons. I enjoy my chickens and some of mine are even pets or others are just to look at (eye candy), still others are old friends, others I keep to be broodies, some for eggs, the spare cockerels go in the freezer (and I enjoy the meat & I like sparing the commercial industry of sales). I also like to show on occasion and thus, I breed my Buckeyes to Standard -- these are my breeder stock. There's not a single purpose here. And we all want healthy birds.
If your purpose was to show or preserve, then you'd better be worried about standards & SOP. Surely, you can repect this point of view. Also, another point I'd like to make is that, for me, the real enjoyment is the trial and error of the breeding. I didn't start with perfect birds, and I get a little aggravated when someone wants the perfect bird from me or they tell me, "I don't want your culls." -- I have heard this a number of times. What do you think I started with? Yes, I started with someone's culls. However, that cull had something I wanted to add to my birds. I got some great culls (One is the best Buckeye I have ever seen -- I still have that male! He produced a Best of Breed at the 2009 Ohio National in the second generation I line-bred him). You see, that cull had something I needed & wanted to add to my birds. He had been bred to SOP too. So, know that it is a pet peeve when you tell me, "I don't want your culls." I will say to you, then you don't have any focus or idea what you are doing. I also ask the person, "Why do you want Buckeyes?" If someone wants a two or three Buckeye pullets and no males & thus, they don't want to breed, why get superb specimens? Leave those superb specimens to those of us trying to improve the breed.
Another aspect: If I am working to improve, say, breast shape but you need better saddle feathers, then for you, there is nothing wrong with my cull. My cull is still going to be better than what you have now, for I am looking for some trait you aren't even focused on. All mine have great saddle feathers but I keep this one or that one for reasons that are my own insight/ reasons. What I see is that a lot of people want instant SQ birds without having to do any work. What is the enjoyment in that?
I also keep chickens for eggs, to eat the eggs, to give to friends & neighbors. See what I mean? I agree with what Stumpfarmer says in the previous post.
There is no right and wrong here (that goes for either end of the extremes).
