theoldchick - you can't post that pic enough for me! That's the cutest pic!
The yellow on the bottoms of the feet must be a bloodline thing; there's such huge variation in lines, and I recall that my very first line didn't have ANY yellow on the bottoms of their feet (I sold them all off, my current bids ar much better quality). So I can see where different lines could have different amounts of yellow, and I certainly would not think they could possibly be BAs with that yellow on their feet.
I'd get back with the breeder you got them from and ask them if they breed Jerseys - they do look very similar, especially when young, so maybe there was a mix-up?
I spent some time looking over my juveniles in the grow-out pen (I think they're 14-15 weeks now), and the one blue boy that I posted pics of a few weeks ago has REALLY grown in the last few weeks - he is honkin' HUGE! The bad thing is that I REALLY wanted to keep a black cockerel, but I keep looking at him and thinking he really ought to be kept...I NEED MORE ROOM!
