Help please Integrated my flock recently - mild pecking, nothing major. Or so I thought. Finally got ahold of my rooster today and discovered his rear end is *completely* mangled. Appears they’ve pecked all of the skin off down to muscle wall around his vent. Sorry the picture is so graphic How do I treat this?? Is it even treatable?? I have Tylan 200 on hand and will go get anything else I need. Thank you all so much!!
