Hello I am new to BYC and to raising peachicks... these are my first four and are supposed to be two whites and two purples. I've been told the white ones won't be able to be sexed until they're about 6 months old, but some other thread talked about bars or stripes that can help sex the other colors. I've done some research, and I feel pretty comfortable keeping them alive for the most part. I look forward though to talking with others who obviously have much more experience with these birds than I do... Thanks..!
