Lump on Zebra Finch's leg or abdomen
Finch with growth
Yesterday we noticed a large lump on our zebra finches abdomen next to her left leg, or more probably on the leg itself. Hard to tell. It's a yellowish/brownish looking sac, which at first we thought to be an undeveloped egg stuck to her, but that doesn't seem to be the case. She was picking at it yesterday, haven't seen her touch it today, and she seems normally active otherwise. Any thought?
