Hello. I am brand new to goats. We bought a 9yr old Oberhasli with her twin now 4 month old does. We started milking her as she weaned them about 2 1/2-3weeks ago. 1 week ago she had clumps and slimy mucus in the milk. Her udder was super hard. We contacted the local vet so isn’t making house calls at this time. He suggested we get the antibiotics from tractor supply, and we did. We followed all the instructions and it seemed to clear up. This was Monday, and it cleared up by Wednesday. Yesterday there was just a little of the slimy yuck, and then lots today. There is no odor and the color is the same as milk.. Is this normal?? She has only one working udder. Previous owner said she got mastitis and it stopped producing on that side. We only get roughly 1 pint per day. I’ve read that she should produce more. I’m wondering if this has something to do with her age. Any help would be greatly appreciated!
