So I am weaning my boys from their momma ( they are 8 wks.) in preparation to send then to their new home soon. Last night was the first night they spent alone in a different pen. I noticed Izzy's bag is hard. How do you guys fix this? Should I milk her out just enough to relieve pressure? Btw she's a fainting goat. And another question about putting weight on her? How would I go about that? She gets purina goat chow and Mixed alfalfa hay. She just seems skinny to me..
