i found a shelless egg on the roost poop board several weeks ago.thats when she started acting this way.at first i was afraid she was egg bound,but she had laid the day before.i bought her in the house and gave her a warm epsom salts bath and rub her tummy.than i felt up in her vent i did not feel anything.i checked her for mites and lice.did not find anything.i had wormed my whole flock in july.i had posted this on byc and asked for some adviced as i did not know what else to do.never got a answer.so i rewormed her last week.she is one of three hens and they all looked ruffled up and just plain raggety in september.and i started seeing lots of feathers in the coop and run.they were in a molt but it was light.all this week i have been finding lots of feathers where this hen roost,and all in the run.so i'am assuming she is in a molt.correct me if you think i'am wrong.i have been throwing some meal worms in leaves that i put in their run and she will scratch around in them for awhile than she will stand off to the side all fluffed up.
