I'm adding here from our recent hatch
Here.
They were from a local lady who raised Brahmas all varieties but only our Buffs hatched.
So these are NOT from TSC or hatchery stock. And I believe that has made the difference in growth rate and being able to sex them early on.
Now, I'm no expert. I Did use the wing sexing tips, day old and week old on shapes/staggered. And honestly it worked for us. Also, the boys are really really slow to feather!
They are currently 6 weeks old and outside. We are coming into winter but we have them warm and a contingency plan just in case .
(Main plan of broody didn't pan out but that's ok)
Photos may not be in any order! I try to click on order but it doesn't always work! Lol should be oldest to youngest (sorry pic overload)
