I've really got to get the bottle-babies (Benjamin, Marvin, Naomi & Seven) out of the house and living outside, but they cry & cry when I leave them alone and I'm too much of a softie. I always give in and let them back into the house. The other problem is, they're still small enough to squeeze through the gate down at the barn, so even when I try to leave them there with the other goats, within a few minutes, they're through the gate and at my backdoor begging to be let inside.
So for now, I take them outside a few times a day to play, and to get used to being with other goats. So far it's not really working - they run away from the other goats and only want to be with me. If they keep thinking that they're human, I guess I'm going to have to see about enrolling them in kindergarten next year!
