To me i had gotten hatchery birds as chicks, i did not care about the quality at the time.
And it is true a lot of people will tell you if you want SQ dont go through hatchery, BUT,
I have a SQ Polish that came from hatchery he does great at shows, when i tell people he is from a hatchery they are surprised.
I also have a Red Cochin bantam that came from hatchery, and when i brought him to show i was told that he has great red feathering, but a too much black in his tail, but he is great to breed with a red Cochin hen, then i would pure SQ from his babys.
I believe you get what you get and work with from there.
I got lucky.
When you order, what you do is, you get the experience learn what makes a SQ out of that breed.
Then you separate your SQ From PQ, and if you get lucky with a lot of SQ you advertise them as SQ.
If you don't then advertise on there production and usefulness egg layer, what ever there quality is great for.
I wish you the best of luck.
Also there is a lot and i mean lot that look for just good cute backyard chickens as pets and eggs layers.
