My favorite hen's personality changed overnight. I've read many other posts about weird behavior and none sounds quite the same as what's happening with her. Then again, I'm a first-timer, so I put it to the group. She's a Buff Orpington, just under 17 weeks when this began, and has never laid an egg. Before, she used to: -Be a leader of the flock, walking around all big and tall -Stand in front and be top dog when I would feed them greens or fruit -Eat a lot -Be friendly and lively and "smart" (as much as a chicken can be...) Now she: -Is always the straggler of the group -Isn't agile and often will stand on the roost rather than sit, or sit under the lawn chair they roost on while the others perch above -Looks confused and stares off blankly or down at the ground, and always keeps her neck tucked in -Is more interested in picking through the dirt than eating favorite things like dandelion greens -Eats but not voraciously like she used to -Is still friendly with me and will roost on my arm, but almost as if it's because she can't muster the energy to do otherwise Weirder still, she seems to have swapped personalities with the other B.O., whom we used to call Scaredy but is now front of the pack. Can anyone identify what's happening? Here are some ideas from my crazy mind: -Could have eaten a weird plastic bauble from the run (artist lived here before us and the ground is full of beads and such), but then they've been in that run for months now and seem to know better. -After this happened I noticed there was a weird orange/blue mold on some small clumps of their food that had got wet and then dried. Could have eaten it and become sick? (But none of the other six seem sick at all.) -They pick at the side of the house, sometimes at the paint. Could have made her sick, but again, the others seem normal. -She's getting ready to lay? But then, as far as I can tell she doesn't have the egg-laying "hips" yet, and her comb is not mature or red, and smaller than that of the other B.O. (who has also not yet laid an egg). -She's prolapsed? Or perhaps it's something else entirely? Would appreciate the help.
