I'm aware that some kind of mineral/nutrition deficiency causes this, and I know it's treatable- I bought a buckling who had one at about this age.
Am I right in thinking it's iodine deficiency? They're are two different does pictured, one 8 weeks, the other 6. They're in the same pen with another doeling and she doesn't have this. Taking into account that every goat is different, I'm still leaning towards a mineral kind of deficiency.
Bigger question- these does are just figuring out "big girl" food, and won't touch minerals. How do I get minerals into them for this?
