My final 2018 posting with a question. The female adult doe shown in the middle of two of her young has an udder-like sack hanging/swinging below her belly. Some have suggested that this is simply an udder, but I don't buy that. It is the wrong time for it to have young requiring milk and the udder is normally situated further back . Also, typically an udder has four teats. On this sack, there is only one teat-like appendix - see enlarged insert. I suspect that the sack-like growth is simply a popped-out hurnia with the teat-like appendix being the navel butten. Any other suggestions?????

Thanks to Len, Co and Trent for I.Ding this condition to be a form of mastitis, or perhaps a tumor.

Note: This Doe hasn't been seen at the feeders for many weeks now after this photo was taken. I suspect that she succumbed to her illness or met another fate, perhaps Coyotes??
