I can sex mine at a day old. And i have been right 99&
Of the time
Along with my bantams
But most time i forget to. If i keeping any
So i have to agee with the Marans can be sexed.
But then i have seen people that will not let you sex the chicks
I just walk away if they don't let me
If the person is selling straight run chicks, why would they let you sex the chicks and pick all the pullets. If I were selling straight run chicks I would pull out what I could get first and that would be what you could purchase. Pullets sell for more than cockerels or even straight run.
Just wondering how many day old chicks you have sexed.
