Thank you Wytsend. I've just been out and bought a brand new mineral lick for her incase she's stopped licking the other one (just to be safe!) she's having caprivite in her feed too.
I asked hubby and my 7 year old who both tested it and they said it didn't smell or taste goaty (it didn't smell goaty to me either) but it was like eating grass ( Only my family could com eup with that one!!)
will keep a close eye on that udder. feed is decreased, will not milk her again as was only doing it every 2 days and bag never really full, already quite saggy when i did go to milk her. looking forward to the new minerals!!
