Bitter Milk Mystery Solved

Well sort of. I know the culprit is Bunny. I've always combined their milk but out of curiousity to see if there was a taste difference I kept them separate. Hunny's milk is sweet and delicious without even the slightest hint of "goatyness". Bunny's milk isn't necessarily "goaty" but it has a bitter taste to it. Now I'm not sure if its because she likes to eat a certain kind of weed Hunny doesn't eat or if its her bitter attitude at milking time. Late last summer her milk tasted fine. Right now it doesn't matter because I give all of Bunny's milk to Porkers since he doesn't mind the flavor and we keep all of Hunny's milk. She is making over 1/2 gallon on a once a day milking so we are getting plenty from her. I just hate that I have to go to all the work of milking Bunny and I give it all away to Porkers. He's doing great on HunnyBunny milk though!
