hey
i cant really see the back one but the front one does look like a little scab, but its an odd place to get an injury i think, i suggest PMing tracie to help out here, im stuck with this im afraid although it doesnt look infected or anything it may be her colour, is she due to shed at all? does it bother her when you touch those marks?
PM tracie to see what she thinks, her username is Drache613.
sorry i cant be of more help.
