My year old Red sex-link had a fair amount of poop stuck to her feathers just below the vent. i washed the area with water and tried to free what was stuck to her feathers, and trimmed with scissors what the water couldn't remove. she doesn't seem to have any issues that i can see....eating well, drinking well, laying well, very active.....any suggestions or advice? Oh, and the other two girls aren't having poop issues at all. FYI. Thanks.
