From what I understand, no. The hatchery used methods like vent, and wing sexing only work within so many hours of hatching. Sex-linked chicks can be sexed by their coloring from hatch on. Other breeds are speculative at best. You're committed to waiting at this point.
So far this has worked for me. At about 2-3 weeks tail feathers really start sticking out. Those that stick out are hens, others roos. Now, I just hatched out 18, 2 different batches. The first batch, now 3 weeks, all look like hens. The odds of all being hens - RARE, so we'll see. The others are not quiet 2 weeks and they look like all hens. So...I either have all hens are all roos!
