I've noticed that a lot of hatchery SLW have straight combs, over half of the ones i purchased had them.
You can see the guy in the front has a big straight comb.
Haha yay a SLW thread! I just got back into chickens this year and got some from a local breeder. Hope you don't mind all the pics xD
These are the 'original five' that I got, first chicks this year.
This is one of the pullets from that batch. We no longer have any of these five, as 3 died...
