Question- One of my CCL pullets is just laying around. She is not interested in scratch or food, but is drinking. I can't see anything wrong with her except her tail feathers are droopy and she obviously doesn't feel like herself. She has been free ranging in the garden for about a month with 12 others. Any ideas of what I can do for her? No bloody poops, no mouth breathing, and nobody else is acting sick. Should I dose her with antibiotics just in case?
