I am trying to figure out if my hen is sick or just a senior chicken. I know Henrietta is older than my other hens. But I am not sure how old, I got her and some of her friends from a gentleman who was selling his mother's chickens. I think she is an Orpington, not sure there either. I let my girls out in the evening about an hour before dark.I have been doing this for about 2 months, I did it last year too. Friday night the girls and I sat out, Henrietta was scratching away in the beds along with the other girls. Saturday morning she didn't come out of the coop. I went in and she was on the poop ledge (the board under the roost). She wasn't able to stand. I looked her all over, she doesn't have bugs, no bites, no outward injuries. I don't see any swelling in her legs/joints. She isn't feeling well because she let me handle her without a total freak out. I even turned her over. Her waddle is good color, but flopping over. Her eyes are round and bright. I took her out of the coop and put her in the "old" coop (version 1 is a nice, but small space, separate from version 2) with her own water, food - I put scratch in the bowl first to intice her. She didn't need incitement to eat. I also fed her a special dose of probiotics and cooked hamburger rice, which I had on hand for my little dog who has stomach issues. Today I gave her scrambled eggs and yogurt whey, which she also gobbled down. She has probiotics in the water. She has her crumbles, which I also mixed in with the eggs. She is panting. It was hot on Saturday- high humility, but the other girls weren't panting. (both coops and the yard is under a big, shady tree in a cool spot in the yard - we are in the deep south). I kept an eye on her yesterday (Saturday), and she stood twice. When she sat down, she was having a hard time tucking her legs under and she had her wings 'out'. Today (Sunday), she was standing a couple of times. She is keeping her feet under her when she sits, but she doesn't pull her wings in tight when she sits. It was cooler today, the humility was lower. She is still panting. She feels warm. Tonight she laid an egg. The shell was paper thin, but the yoke was bright yellow, no blood spots. She has normal stool, not loose or bloody. I don't want to keep her isolated, but I don't if she is sick. Any thoughts?
