Thank you I will get some epsom salts in morning and maybe pop her to vet and see if he knows anything, although he is not an avian vet but he did look at one of my chickens before (here policy is very much they eat them not treat themwould like to help this little lady.
Thank you I have googled and looks a bit like bumblefoot but no soft infection inside etc just hard solid lump and otherwise she is in good health, maybe a trip to vet but no avian vets here.
its possible the infections or the foot has formed a hard callus skin layer
soak in warm water to soften skin and then clean it up in epsom salt
eventually if it is bumble foot the tell tale black plug will be seen
