I have a pullet (10 months old) that a week ago started acting a little slow... she separated herself from the rest (two other 10-month-old pullets and two 5-years (or more) old hens) at mealtime, waiting to eat until the others were done. Then she would often head off by herself. She quit laying. At the time I was doing a little coop maintenance, so I thought maybe she was thrown off by the changes. A few days later I noticed some heavy pecking-order stuff going on with the two old ladies and my buddy Indie. So I separated them (the bullies) out from the rest for most of the day, and she seemed to be improving... for about 2 days. Now she's really slow - but still stands, walks around and hangs with her peeps. She's just more puffed up and much slower than they are. She doesn't eat as much or as early. She waits to come out of the coop... she's drinking, but not like the others. She's usually a real pill to catch, and she still is, but she's calmer now when I do catch her. She's usually a non-stop talker (clucks and clucks at me non-stop), and she still is, just not nearly as much. @TwoCrows and I were thinking mabe cocci, so I started them all on a round of Corid yesterday. (It's been 24 hours with Corid.) About 36 hours ago I noticed her shaking her head a bunch, lightly, but definitely a shaking. So I trolled the threads here and did a real examination on her. Here's what I found. Nothing. - her ears are crystal clear - there are no bugs on her anywhere (ears, under wings, vent, etc.) - her feet are normal temp (no fever) - her breathing is normal - no runny nose, no watery eyes Throughout it all, her crop has been empty in the morning and has food in it at bedtime (although not as much as usual). They were wormed 3 months ago. I have a vet that can see chickens BUT it's a hefty $$, and this month is not feasible for the hefty $$. I'm wondering if anyone has any thoughts? None of the others are in the least bit affected. Thanks in advance for any help!
