I have 3 does that have been bottle fed. They are now about 12 weeks old and getting 12 oz of milk 2 times a day. They get to be outside in the yard to graze most of the day and a bowl of fruits (strawberry’s bananas okra blueberries blackberries you name it lol) I also give them some “goat treats” they’re berry flavored pellets. they’re eating solids well but I’m not sure they’re getting enough to wean. What grains should I start them on? And should I give any extra greens or vitamins at this time?
