Elizabeth, sorry to hear about your australorp!
eggxelent, I wouldn't feed it to them until they start laying. The laying feed has extra calcium, which they really don't need until they're making eggshells regularly.
Seth and
Tyler, I plan to be there. I'm not sure exactly when, since we still don't have a vehicle.
Kim,
. That's about all I have to say there.
DarlingMommy, I've often seen those breeds on Craigslist. I know Green's Feed is getting chicks in for another month, and you could call and see what they have. They're not laying hens, but you'd probably get the breeds you want.
