I am new to chickens, but do understand what pasty butt is. This RIR chick is constipated, not suffering from pasty butt. She chirps every time she is trying to poop. This has been going on for a couple of days - I was hopeful it would get better with the introduction of leafy greens to their diet and also corn meal in their food. She is able to have movements every time she tries to poop, but it is obviously painful for her and today, her bottom is a blackish color under the skin. Also, her vent was protruding today when trying to poop. I am very concerned. As previously suggested, I will try gently flushing her vent. Does anyone know the prognosis for this problem? I realize this chickie could die from this problem, but I am worried about her timeline! Is there a sign that it is 'too late'? The discoloration of her bottom is concerning.
