I am going to post PAST photos of the Austra Whites:
Here are the 1st shipment at approx. 5 weeks of age:
Note that the pullet (left of the waterer) is already showing the black legs and the cockerel (on the right) has yellow legs. The chicks arrived as two-day old chicks and both sexes seemed to have yellow legs while that young. There is also black on the beak and comb areas.
Here are the 2nd shipment at approx. 2 1/2 weeks of age:
(I think they were about 1 1/2 weeks old when I received them.) At this age, they acted similar to the earlier shipment, and did have less black 'speckling'.
A pullet from the 2nd shipment at 7 weeks of age in the back:
Note the absence of black on the legs or head, or in the feathers. Five or six of the pullets have a very few black feathers.
