So, I got six new baby chicks yesterday. We have one Pearl-White Leghorn who was fine yesterday. When I checked on her this morning I noticed that there's a line of wet feathers down her chest. I watched her and she goes over to drink and every time she drinks a little runs down her chest. I'm concerned because none of the other chicks have this issue, so I'm afraid she's sick. I'm new to chickens, so don't even know if this is normal.
