I have a beautiful Americana Hen. I got her along with two others when they were 2 weeks old. She's 7 months now. She's not laying eggs yet. I've got 6 other free ranged hens in my enclosed yard. Everybody was doing fine when I left for vacation a week ago. I came back today to find this particular hen acting ill. Her comb seems shrunk and purple and she's acting lethargic. She did eat some cracked corn from my hand but made no attempt to move around to get more when the other hens jumped in. I think she feels thin but I'm not experienced at that. I do have a hen sitting on several eggs and half of them 'disappeared' one afternoon two days ago. The pet sitter opened the coop in the morning and when he came back in the afternoon 6 eggs had gone missing from the cohin's nest. There was no sign of broken eggs anywhere. I have no idea what could have happened and I don't know if this could be related to the Americana's illness. I don't see any trauma on her. I'd appreciate any ideas about what's going on and anything I can do for her. I did lose a hen about 5 months ago to abdominal peritonitis. I took her to the vet but it was too late and she had to be euthanized. We suspected that she had an infection from a dog grabbing her that happened 6 weeks earlier but couldn't be sure. Lots of info but I don't know what related and what isn't. Thanks for any ideas.
