I have a Welsummer girl about 9 months old. She's fluffed up and lethargic. Tipsy. Weak. her face seems pale, and her poop seems much more watery than usual. We've had a somewhat mild winter with weather going back and forth between sunshiny and mild to suddenly freezing with temps in the teens and twentys. I have a light in the hen house. it's low wattage, but as close to an incandescent as we could get, just for a little more warmth. The hen house is not well insulated, so it's not a drastic change to outside temps, plus all my girls like to roost outside of the hen house. I ran out of feed last month and couldn't drive (surgery on my arm), so I bought a bag from my brother in law. Crumble, which I hate cause it always seems to turn to powder and just seems wasteful as it clogs up the feeder and never seems to get eaten as much. When I noticed how skinny my girl was I just dumped the feeder and refilled with pellets instead. She is eating well, but not gaining weight. (this all started Sunday.) Since then I have isolated my girl and she's being fed pellet layer, a little scratch mixed in, scrambled egg and canned corn first thing in the morning. She no longer wants to stand or walk as much and still hasn't put on any weight, so we brought her in the house. My other chickens are doing great, although now 2 are trying to pick on her (which is one reason shes now in the house) hubby and I are wondering if this could be a combo of molting, trying to grow new feathers with a lack of proper nutrition (the powdery crumble), and then getting picked on and possibly being pushed away from the feeder? She was eating well till this morning, but in her defense, her crop is really full. I did massage it some and it has the consistency of soft clay, so not overly hard. No sneezing (unless she gets too big a mouthful of water), no blood in her poop, no coughing, vent looks ok. I lost another hen with about the same symptoms last month (3 year old RIR) what else can I do? any suggestions?
