1) What type of bird , age and weight. seven 7 month old pullets ( ee, australorp, delaware,columbian wyandotte,SS, welsummer, barred rock). Hatched april 12 : hatchery birds 2) What is the behavior, exactly. : active and alert but all are shaking their heads, no nasal discharge, no respiratory distress, no wheezing... 3) How long has the bird been exhibiting symptoms? 2-3 days since a few days after moving them from a large outdoor paddock to a 14X16 stall, bedded with pine shavings. Moved them in due to hawk losses in the last 10 days of 2 broodmates. 4) Are other birds exhibiting the same symptoms? all seven, fairly equally 5) Is there any bleeding, injury, broken bones or other sign of trauma. NO 6) What happened, if anything that you know of, that may have caused the situation.: wondering if stress could cause this. Closed flock with no exposure to other chickens. Some wild bird exposure when in the fenced paddock. 7) What has the bird been eating and drinking, if at all. : all eat layer pellets, occasional handful of BOSS, had been grazing as welluntil 4 days ago 8) How does the poop look? Normal? Bloody? Runny? etc. Normal poops 9) What has been the treatment you have administered so far? no treatment, they seem otherwise healthy 10 ) What is your intent as far as treatment? For example, do you want to treat completely yourself, or do you need help in stabilizing the bird til you can get to a vet? Will talk to avian vet if needed 11) If you have a picture of the wound or condition, please post it. It may help. 12) Describe the housing/bedding in use : until 4 days ago they were in a 1/5 acre grassy, fenced in paddock and locked in a 4X8 coop with excellent ventilation and bedded with shavings at night. Lost 2 to a hawk in last 10 days so moved the rest into a stall( 14X16') in a well ventilated 3 stall barn, clean and not excessively dusty (but more so than the paddock of course). Bedding is pine shavings( same as in the coop). Hay in the nest boxes. lights are on from 7 am to 8 pm. None of the birds appear sick, fluffed etc. There is no nasal discharge, eyes are clear and bright, feathers are sleek and I have not seen any mites or lice. No gaping. Eating but a bit less since confined. Crops appear normal with food in them, not overly large. The SS and barred rock have started a molt with loss of feathers and many pin feathers on head and neck, The others do not appear to be molting. Egg production is down to 0-2/day but I attributed that to the loss of my best layers (of course) and decreasing daylight and stress.... I'm wondering if they may be sick or if this could be a stress issue Thank you for any help!
