Gracie. What to do now????

She had improved so much since the feather cyst burst and certainly seems like her old self again, but just brought her in for A/Bs and to treat the burst and there is another one right next to it.  Have sprayed them both but don't know what else to do.  She doesn't seem to be in pain at the moment and isn't doing the heavy breathing anymore.  Can anyone suggest anything please?      

I would agree with D here, Jinty.  Gracie is already on A/Bs and you have sprayed the area.  Just keep an eye on it and let her natural healing processes kick in.  It is very hard to see one of your hens suffering; however I'm sure you are doing all you can.  Good Luck!
