Since early this morning my most active chick has been cheeping loudly. The others are just fine, eating drinking and all. Mr. chirp seems fine otherwise too. He/she drinks, eats, picks at grit. And whenever I put my hand in the brooder he pecks at my fingers thinking I have some egg whites. They are about one week old or 6 days today. Is it something I should be concerned about? My other chicks could care-less about sticking under the lamp, they are just fine. I think I'll move it a little closer. Anyone have any suggestions in the meantime?
