Can you tell as chicks what color eggs will be laid? I just hatched out 6 chicks from a gal in my town who says " the rooster is pure white and I have white chickens and some barred rocks etc. the eggs hatched out all yellow with white on there heads, 2 came out all yellow with about 6 black dots on them. There a week old and the wings are growing feathers that are white/ extremely light yellow. No color on ears , just yellow fur on them . When can I tell the color eggs they will hatch?
