I have a 13 month old EE hen that I got about a week and a half ago. She laid 5 eggs out of 7 days, then starting Monday, I noticed her tail was drooping and she doesn't seem very peppy. I also haven't seen her eat at all today. She hasn't laid at all since friday... what should I be on the lookout for? I'm totally new at this, so I've never "checked a chicken's vent" or checked for mites or anything. She had just come of a worming treatment the day I got her (Ivermectin??? Did I get that right??) I'm just not even sure if I should be worried or not, but of course, I'm freaking out!!! Damn chickens get under your skin so quick! I love her!!!
