my almost 7 year old DNA male conure has a “belly” between his legs. his annual blood work is good. I started giving him milk thistle and aloe (lily of the desert) in case it’s liver issues. is there a test I need to request to check his liver? he has always been flighted and my flock is out and about 09-10 hrs a day. they eat tops pellets and organic steel cut oats, organic chai seed, organic oat groats, treats include walnut piece, tiny almond pieces, organic anise star segment, piece of pecan.
