Back to the question about feather sexing....
Not all breeds can be feather sexed and it is not 100% accurate, however, once you practice and track your own accuracy, you will find it is pretty reliable with many breeds.
I have Minorcas, which are not in the category for feather sexing. On the other hand, I have a batch of Buckeyes that are 2 weeks and I am quite certain of 16 I have only 10 cockerels this time.
Considering last year overall my percentage was 70% males, this is wonderful.
I am looking for ways to sex my chicks as accurately as possible on my own since I will have A LOT of extra males and I want to caponize several of them this time around to have better quality meat birds, so feather sexing is one way I can do that.
I think Wyandottes were another breed I have had a tough time feather sexing, and Hamburgs too. I am wondering if the Med breeds all fall into the same suit with this topic?
As for the chicks in the pics, #2 male the rest female.
You can also tell on some as the feathers grow out more by looking at the shape of the wing feathers. The cockerels feathers come in more blocky looking and the pullets more elongated. If I can get a picture, I will post it to this thread to show what I mean.
