Relaxed Farming - our farm in your classroom

We have an interesting puzzle today: the pictures below are all of Nutmeg, one of our pygmy goatlings - she is a gorgeous goat in both looks and temperament and in the latter definitely takes after her mother, Thyme! Take a close look at the three photos though - can you spot the difference? In the middle one she does NOT have any black markings under her eyes and yet in the other two she does. These photos have been taken several months apart so, in order, we have Nutmeg at nine months, then 13 months and finally 18 months (she is currently 19 months old). When she was born in February she did not have the black markings, they first appeared in the autumn that year but then had disappeared by early spring this year. And last month they began to show once more. When they appeared the first time they looked like black streaks from her eyes but they then just seemed to travel down her face until they were no longer there...
It is quite normal for young goats to take a while to develop their full colours and so in their first few months they often show different patterns or shades - when Nutmeg was born her fawn colouring was much darker but it gradually got lighter as she grew older.
It is also normal for goats to shed their coats, in the same way as chickens moult, and they do it for the same reasons - to replace old fur/feathers with new that will then keep them lovely and warm throughout the winter. You may remember Cheddar shed her coat a few weeks ago and Gorge is now moulting as well (and we might add not looking great...).
We think Nutmeg's black markings are all part of her moult, in that her spring/summer coat is pale but when she then grows her winter coat, this contains a black pigment which gives her the black markings. Last year she had black on other parts of her body as well, we will have to see if the same happens this year!!
With or without her markings we think she is still a very pretty goat: what do you think?
