Hi i have got some zebra finches they have just had 3 chicks they are about 3 to 4 weeks old not 2 of them are dark gray and one is almost pure white. I think i read somewhere that when they hatch they are all the same coulor is they white one special so it will stay white or are the 2 colours male and female? I dont think your able to tell the diffrence till 9 months when they have there first molt. Any help will be greatfull i just want to know if the white one will stay like that?
