Hi I have just noticed that our cochin bantam rooster has very sore looking feet...he was fine 2 days ago and i didn't notice anything yesterday, the 3 hens do not seem to have a problem. They are 1 yr old and until a couple of weeks ago were kept in their but my husband has taken to letting them run in the garden...it doesn't look like the pictures of scaly leg mite ...please advise problem and possible treatment
