Oh goodness. It acts just like a male strutting itself around. How can you tell sex?
I would be thrilled if it were a hen.
I will have to read up on all this split business. I don’t understand it at all.
If you look above on the top of the Peafowl page there are a list of 'Stickies' that will take you to the general information on housing, care and genetics, it is a great place to start learning.
Splits are references to hidden genetics that you can not always see. When splits to sex-linked colors pop up like your chick did then you know that it is a hen because a hen can not be split to a sex-linked color. It does not matter what color hen your cock breeds, half of the hen chicks will be Cameo, if the hen is Cameo then you will also get both Cameo cocks and hens.
