Can you bottle feed them? Milk the mama n give it to the babies or get milk from someone? I know it can be hard if they are untame. There is a goat rescue up here in Arlington that probably has milk if you need it. I know it takes a lot of time... Maybe you could find someone to bottle feed them if you are unable.Sometimes you can get the doe to nurse, but more often she won't. Even if you hold her to let the babies nurse, when you go away, she won't let them. And, they need to nurse very often. They can also get pretty aggressive, and with horns they can be dangerous. I've got one in the house, gave him some milk and pedialite, but I don't think he'll make it. They won't starve. If they don't show any improvement, they will be humanely euthanized. I can't stand to watch animals suffer. I went through this with a doeling 18 months ago. I had her in the garage and tried to nurse her back, but in the end she was too weak too stand. I'm sure the look in her eyes at the end was asking me to help her out of her suffering. So we did. And then I cried.
If the other doe had kidded at the same time, or a bit earlier, I think she would have taken them. She was such a good momma last year. This one is new and not very tame. We'll do our best.
