I got her yesterday, she is 3 days old as of today. Out of the three, she is the only one that is sitting down and closing her eyes, like she is trying to sleep. The other two, when I try to pick them up to check if they're healthy, they always try to run away, but this one, it's a buff orpington, stays in the place and continues to sleep. She sometimes has these energy bursts where she gets up and eats/drinks, but then goes straight back down. What should I do? All the posts I read said that ____ barely survived or ______ died. She isn't chirping and doesn't play with her two buddies.
