i have a old hen (gramdma) that is about 6 years old she will some times get a poopy butt. today she just sat on the pearch after i let everyone out. i pick her up and knew something was wrong by the foul smell. i check her bottm to find maggots around and below her vent i quickly got her in the house and began cleaning her with dail soap , perioxide,lots of water i soaked her bottom in the sink and when i was done dry her off as best i could . removed what i could see and sprayed her with bule coat. I FEEL AWFUL should i do any thing more. i put her back in the pen after i disinfected and scrubed all the perches with bleach and water then i sprayed melathion every where to reduce the flys.strange thing is that i have not had many flies in the barn. but she does rome the yard with the rest of the flock. is there anything else to do?,should i keep her away from the other birds?
