My dog grabbed my new hen (she's a Red Star aprox 18 weeks)! She's not dead, but I fear may be soon. She's laying down/squatting and will stand up. This only happened two hours ago. Her breathing was rapid but seems to have relaxed. I haven't seen her eat or drink. What should I do? Should I put her in the shed separate from the rest of the girls for the night? Leave her be? I'm BRAND NEW to chickens, haven't even gotten an egg yet. Thanks!
