Yep, that looks like fishtail to me. You can give copper as often as three months, so it's probably time. Dosage for copper is 1 gram per 22lbs.
Is this fish tail
My goats had bolus’ February 20th and they have free choice purina goat minerals w 2500 ppm copper. They are not on well water. Their coats are a little rough and I noticed today their tails are looking fishy. Should I give a bolus again?
