my luck is not so good. 4 weeks ago I got 4 BR pullets from the feed store with my son. Now that the birds are 4 weeks old, it's obvious that only 1 was a BR pullet. I've got 2 roos (1 BR and 1 Australorp) and 1 australorp pullet. Hmm...I understand sexing at the hatchery might have been off, but I'm surprised that they mixed the BRs with the Australorps.
