Hi Diane,
You are right to not integrate them w/your flock until you know they are ok.

If you try e-mailing the pictures to me I can post them for you. Just click on my page and there should be a link to my e-mail.

What are you feeding them? Do they have starter, or just scratch feed? Have you seen any lice crawling on them? Were they in with adult birds where you got them from? Are they bloody? What were the conditions of the other birds where you got them from, did the chickens have dirty butts, was there a lot of poop in the chicken yard, a strong ammonia smell, stuff like that? ITA with the above poster, isolate them from your other birds because who knows what they could have. My chickens were infected with 3 different types of parasites from chickens my husband picked up from these dirty people who raised filthy chickens. You might want to go here to see what you can do for them. Poor little chicks!

Here's the picture of Diane's chick.

Sorry I didn't get back to you sooner. It looks like they have been pecked by other birds to me. Were they getting picked on where you rescued them from? Do they have any other symptoms (not eating right, pasty butts, etc)?
