I've got my first little of piglets. 7 healthy Yorkshire x Old Spot almost 5 weeks now running around on 3 acres of pasture. When they came out their skin was nice and white and only 3 had spots. Now everyone is getting little black/grey spots. I'm wondering if its mange, though i don't know where it could have suddenly appear from or its a zinc deficiency? the little buggers wont stand still long enough for me to get a really good look, but they don't seem thick or crusty. just....grey spots developing on everyone.
I sorta got a picture, I'll try to get some more today. any ideas?

learn permaculture through a little hard work and get an acre of land
