I have a SL LF Cochin Pullet - came from a hatchery (I assume) as she was "sexed" and got her with 3 other "sisters" one of which is a beautiful Rooster! ... their about 5 months old. about a month ago - she started acting strange, didn't want to move around much, came out of the coop and would go over and hang out under the lilac tree instead of going out across the yard to scavenge with the others... So I separated her into the chicken ICU - quiet, darker place for her to rest and not be picked on. It took about a 1.5 weeks until she really came around to her perky self - and wanted OUT ... she was eating well again and a drinking - but I had to bring the water right to her beak and really encourage her to drink and she'd take a few sips - I added sulmet to her water for the week per directions and once she was active and eating - I let her back out with everyone. She hasn't been as "heavy" as the other since. but she had been "normally active". Friday Day - I saw one of the boys chase her pretty far across the yard... but no further than they have normally adventured... That night she didn't come in to the coop so I went out hunting for her- found her "resting" under the brush pile as if that's the place she choose to sleep... So I brought her in and placed her alone again... figuring maybe she just needed some good quite rest. Saturday I went to put her outside and she tried to ruffle and itch herself and she fell right over! So again - she's back in ICU ... but I don't know what she has... The info age:5 months old breed: LF Cochin sex: Pullet living: free range, and come into their coop at night feed: fresh water daily, poulin layer crumbles and a few handfuls of scratch every now and again scattered in the yard (for 30+ chickens) symptoms: lethargic, off balanced, weak, doesn't want to eat or drink, empty crop, yesterday there was green poo, today really white and pasty (assuming because she hasn't eaten much) Treatment I've offered her just plain water for the time, scrambled eggs with a bit of olive oil and crumbles any clue what it is and what to do/offer her?
