1) What type of bird , age and weight. Buff Orpington, adult (at least 2yrs), i don't have a scale (she is...was... a big girl) 2) What is the behavior, exactly. desceased now (non-emergency...my concern now is for the rest of the flock) she had been fine. today was hot & all birds were panting & a few were keeping wings out to cool off. 2 hrs earlier i had given them fresh water & they had full access to that and they have plenty of shade from the tree & their "dugout" Happy was in the "dugout" under the raised coop, laying on her side (almost on her back) with her head on the ground. i picked her up & her neck was floppy & she had her mouth parted. checked her for wounds...nothing i grabbed a new frozen 2L for the coop. i tried to give her water & she wouldn't drink, so i used my fingers to drip water into her mouth. i tried to hold her upright & she would just flop over. i spread her wings out & tried to get air to circulate around her. when i went in to get a wet towel, my husband yelled to me that she passed (her wings extended & shook & then she was still) her comb, ears & waddle immediately turned purple 3) Is there any bleeding, injury, broken bones or other sign of trauma. no 4) What happened, if anything that you know of, that may have caused the situation. the only thing i can think of was the heat. no change to feed, flock or routine 5) What has the bird been eating and drinking, if at all. commercial layer feed, access to garden, yummy bugs & snakes, access to compost pile & WATER 6) How does the poop look? Normal? Bloody? Runny? etc. well within normal runny range 7) What has been the treatment you have administered so far? see #2 8 ) 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? she is now in the freezer til i can decide what to do tomorrow. hubby thinks maybe we should cremate her instead of bury her...this is our first (non-meat) chicken death & we're unsure what to do Thanks in advance for any light you can shed on my sadness. This was my FAVORITE hen. She was soooooo docile & loved to sit in my lap & have her waddles stroked.
