Thank you Aunt Sally and JMOMIMEY,
Yes it is that coral colour but it does look like and feel like a lump of cooked meat!
What would cause a 'lash' Aunt Sally? Would it be an infection? All three of them look well, one is a little quiter than the others but to be honest I put that down to the freezing weather. She is always the one on her own, last one in from free ranging, last one to bed in the evening.
