I don't know that this is the same as 'pigeon fever.' 
When Valaba got it her legs swelled up like elephants
legs.  Dr. Byerly explained that it was blood
collecting in her legs.  That her blood vessels were
bursting and hemorraging inside of her.  It was one of
the most awful things I have ever seen in my life.

There was a coincidental outbreak of distemper on a
facility down the road from us.  We suspect that was
the originating site of the bacteria that got into her
system (probably from flies - dairy cattle area) which
caused her difficulties.  At any rate I'd like to know
if Pidgeon Fever can lend itself to the same type of
situation.
