This started with three of my buffs at about a month. I have already lost one and the other two are still separated, not really improving but not getting worse. Thanks for the tip on yogurt. I am going out now to feed them some. They seem really weak on their feet and wobbly although I see them drink and eat food. I have a guinea that has adopted them all and occasionally she will get in their basket. Perhaps I should just bring them inside the house. I'll keep you all posted
