Sizzles and a frazzle... questions....

[NDgoatgirlNV]

I was just given these little cuties and was wondering if they are able to be sexed yet.
Also...I have a question about my little Frazzle who I think is the cutest thing ever...will it need any special care or are there things I need to worry about genetically as it grows?

Its a little early to tell, but the first and second chicks might be roos.
