So, yesterday, I noticed that one of my Wyandotte hens had a poopy bum (she's my largest and prettiest). When I pulled her out from my coop of 55 others, I noticed a large bulb near her vent that was squishy, which I knew was Ascites right away. Around her vent, she also has obvious lice egg sacks and lice running from there up her back. I soaked her in a warm Epsom salt bath for about 30 minutes, dried her off and put her in isolation. She is lethargic and doesn't eat much. I am considering culling, but I haven't done anything yet. I also live at a high elevation: about 3000-4000 ft. She poops fine and we recently got her and a few other hens and two roosters from a home who could no longer take care of them. Like a novice, I didn't give them a full check-up when we brought them home, but I did isolate them from our Plymouth Rocks. No other chickens have bald-spots like her, but I haven't fully checked them all. Should I cull? If I do, would she be safe to eat? Drain, treat and hope for the best? If I drain her abdomen, how often should I repeat? It's also time to clip my flock's wings again, so should I check all of them for lice? They always have sand in their yard, but should I add Diatom Powder? Please Help!!
