That looks like they're warmer- they're not all clumped around each other now.
Now, we should look at your bedding. That newspaper is kind of slick and can cause splayed leg in chicks, which SUCKS. I would suggest that you get pine shavings as bedding. In the past, I've also used dirt. You'll need to get a bedding that isn't so slipper for them.
You are doing such a great job with them. They are so, so lucky that you found them. I can't wait to see them grow up.
Did you know that baby chickens are called chicks and baby turkeys are called poults? I recently learned this. So interesting!
