Crowing
I dont think the bumble will cause low weight unless she has trouble getting around (to the food), i would follow the paricite route, get some dewormers if you cant afford a fecal float. Keep up with the iodine, anriseptic every day helped my ducks with bumble, i didnt wrap them, they were on grass, so i would disinfect then hold them for about 5 minuets to let it work then let them go. Also corn can help fatten them up.
