Both feeding together. Some of the chaffinches have got tumble foot (or bumble foot - I can't remember which) and this is a disease that affects their feet and is really untreatable unless you can catch them. It sadly results in them losing their feet.
This infection is much more likely to occur in captive animals than in those in the wild since it is caused by inappropiate perching or perching too long. Too bad, wish you could catch them
Oh that's horrible. ( Especially as we have just discovered Jinks has a 3rd injury to the same paw - at least we can go to the vet & get antibiotics etc etc.) Like the shot!
@moominmomma We have goldfinches, greenfinches as well as chaffinches coming although the greenfinches have tailed off a bit at the moment (forgive the pun)
