Air cells? What do I need to know?

On another note... These are most likely going to be leghors or leghorn X's and I am finding on YouTube that Leghorns are feather sexable on day one. I am hoping this plays out, any experience with that?

No.

I think they had a couple temp spikes at first. I agree hatch rate can vary widely.

No.

This is the video I saw, then I came and searched feather sexing leghorns here on BYC and there was not much to read, other than its about the K gene and wether one copy or two... I will feather sex and as long as ALL of them are not the same I will then take the suspected male and try my hand at vent sexing and hopefully confirm. Theres LOTS of youtube vids on that. I want to eliminate the males early as possible while they can still be consumed by my friends snakes. Sounds horrible but better than being ground alive for dog food and the snakes need to eat.
