Every morning when i replenish their seed i notice their bums are crusty with dried poop where they have been dropping into their seed dish overnight. ( obviously they have never heard the expression of " Dont S*@$% in your own nest......

Just wondering if i should be concerned this could lead to a health problem ? Its not like their vents are BLOCKED with dried poop, just crusty all around the area. Any ideas or opinions, anyone ?
