When checking the nesting boxes tonight for eggs I noticed a fishy odor. One of my chickens who is currently broody has a “wound” under her right wing that is filled with brown hard secretion. it looks almost scabbed over, and the “hole” doesn’t look like an injury. it looks like it’s been there forever. there is no blood or torn tissue. one portion of it looks like a scab and the deeper portion looks like the brown stuff is coming out of the chicken. pictures are graphic:
it’s extremely difficult to explain, please look at my photos. i’m not sure if i should chip away the the brown stuff to reveal what is underneath. i’ve never heard of or seen anything like this please help! she is about 1 year old and has her back feathers plucked from mating. maybe his was a puncture wound from a rooster and has become infected has turned into this? the area doesn’t appear to be red or swollen.
