One year old rir-bo cross very healthy rooster until last night; wasn't on the roost and just thought the hen he's in isolation with booted him off the roost (in isolation due to conflict with my big ol' head rooster) This morning, just now, all somewhat hunched but limp, not moving. Comb is purple-dull, not eating even corn, or drinking. Breathing is very slow. Appears cold. When I moved him inside, clear fluid dribbled from beak and made a very sad little noise. Crop is loose, somewhat spongy. He was out of the enclosure at will in the garden yesterday acting all normal; being out in the garden is also the usual routine. I'm thinking injured or sick - something smells like an injury but I can't find it; doesn't seem to be sour crop. Will look again.
