The local pet store owner asked me to sex a bunch of white/mix zebra babies. There was only one true white in the lot and based on beak color it is a female. As for the others I believe they are mixed with normal greys and have come out with light buff spots on them. They have tear drop makings on thier faces but other than that nothing but muddled buff color. Three of them are very young still have black on their beaks so beak color can not be a good judge here. I have only had them in my care for a few hours so I have yet to hear any singing. Is the song the only way to tell or is there something else I can go one.
On another note I told the owner of the store to never take birds from this person again. She lied about them being sexed she doesn't even know how to sex normal greys she brought all males.

She said they would be banded, no bands. She lied all the way around and was afraid of her own birds. She would catch them with her hands in a transport cage she needed a net.

I am by no means an expert but know better then this woman. I had to tell her she needed to stop breeding them because the offspring would be weak and her hen would die from contunied breeding.
Sorry for the misspelled words, Any help would be nice. I'm hoping I can sex these babies by Friday and get them out of my house. I'm discused with the whole thing. People.
