Maggots in vent of 2 year old black sex link. Hard molt in Feb/Mar and has not laid since then. Checked her last month and could not feel any internal eggs. 3 days ago found smelly liquid poop and now realize it is hers. Yesterday and today slow moving and not readily coming out of coup. Had time today so got her and turned her over and matted feathers around vent and could see maggots moving just inside. Vent very relaxed, very moist and loosely open.....dark in color but don't know if that is normal color. Bad odor. What do I do for her? Bath her bottom part, clip feathers, clean off poop, remove visible maggots. Is there a chance they are up inside and how do I care for that? Flush with what solution....like douche?
