Here is a picture or link to a picture (not sure how it will show up here) from the Crested Breeds Club of Australia:I was told and sold these as Pure Bred Lavender Blue Araucans, but now that Ive looked at them im not too sure- the lady sold them to me for Australian $40.00 for both of them(I live in Australia). Have i paid to much for them??? Sorry they look a bit scruffy, but nothing a little care and new molt wont change. One laid me a Lavender Blue egg yesterday which i was very happy with so thats one point to pure bred and they are a slate color and have slate legs so that another 2 points, just not sure on feathering, it is like down or silkie feathering and the comb is really strange.
Hen 1 is in the nesting box and hen 2 is the one standing up she is much bigger.

I remember reading that they are very different from what we have in the US and that one does look similar to your bird.
