When my week old chick drinks water, she doesn't go back down for another sip as fast as my other chick. I thought maybe she just likes to savor the crisp taste in her mouth or something. I also noticed that she always makes a crowing gesture as though she was an adult but doesn't make a sound. I've always thought that was just her yawning or something. Just a second ago I saw her throw a little bit of water back up and drink it after she took a drink and still didn't go back down for another. Is this normal? Do I need to add something into her diet? Is she too excited and stressed?
