Elissa, a one-month quarantine is really a good idea and we have the space for it, too. Plus, I think it will take them that long to grow enough to be in with the big girls at the bottom of the pecking order without danger, too. We took a look at them this morning - they are eating like there's no tommorow!
They can see the other chickens accross the way, but are not near them. They appear to be lice-free, but got the treatment anyway, just to make sure. We'll be checking for worms, too.
JenellYB, they look like super-skinny versions of your avatar, one more darkly patterned than the other. And they are very sweet - they ran to me this morning in their cage, looking for food, which I gave them. DH says they must have thought they died in the night and woke up in paradise. He's right - we live in a paradise here. I'm so glad we got the new chickens. Well, I am off to watch "chicken tv" for a couple of hours.
Thank you everyone for your advice. You are all very kind.
