My old girl has a bad opened sore on her backside

[Rbillingslea]

Hello- I came home from vacation to discover my oldest chicken, Daisey about 7 years has an open sore on her backside ( by her bottom). I will begin to keep her inside and treat her sore with the hopes that it heals. Magots have gotten to it, which I have done my best to clean out and will continue to do so. They are so disgusting... My poor girl. I am hoping someone might have an idea of what would cause this. I was wondering if it a pressure point from being old and sitting too long? A tumor rupturing? Anyone else have this ever happen to their chickens?

Welcome to BYC.

It sounds like she has Flystrike. Which is where flies lay eggs on the skin. The eggs then hatch and start to feed/cause damage.
You did well bringing her in, you may need to bathe/flush the wound for a couple of days to make sure you get all the maggots out.
Give her a good soak in an epsom salt bath and flush the wound good.
Depending on the size of the wound, you can apply some antibiotic ointment like plain neosporin, for a large area Vetericyn spray may be better. You may need to repeat, soaking and apply ointment for several days.
