there really shouldn't be an age restriction on this as it would be nice to see what they looked like as chicks best thing for this would be a progression series from chick to adult as no 2 mixes look alike as chicks nor adults. i have 6 silkie/d'uccle mixes 2 adults looks like buff Columbine, 2 chicks with different colored feathers coming in and 2 solid black chicks and each one looks different
although i looking through the pics i also would love to see what they looked like as chicks
