My goat delivered her first babies last night - a beautiful little girl, and a boy. I keep seeing the little boy try to nurse - he gets on the teat for a few seconds, and that is it. I haven't seen the little girl nursing at all today, and when I put her under her mom and try to offer her the teat, she doesn't take it at all - just walks away and lies down. Is this normal? Are they tired after being born? I'm worried about the little girl.
