She seems sleepy, her heart is pounding and her body is vibrating because of that. She seems out of breath, too, from time to time opening her mouth. She's a Delaware, the picture of health, good color, no injuries, no weird poop, cant get into poisons, eats layer pellets and a bit of scratch in the a.m. The coop is clean (their part is new, really). I'm worried I'll lose her and I have no idea why. No discharges, eyes are clear, nares are clear, cant feel an egg, she just seems like her heart is going to explode, no abnormal poop. Found her under the roost in the shavings, and at first thought a dustbath, but she wasn't moving. Thought maybe her first egg was coming so I put her in the nest. She was very subdued and sleepy and stayed. After awhile, when I checked, I realized her heart rate was through the roof. I'm stumped.
