My Nigerian Dwarf goat Charlie gave birth on Sunday to twins, and on Tuesday my other goat Cassie gave birth to a single. They are separated in a 10X12 stall at the moment. I have tried interacting all of them and Cassie (on a leash) is extremely mean to the twins makes funny noises and wants to head butt and Charlie does nothing to protect them. She does this same behavior with my Lab and barn cats before she had a kid. Whats the best way to get them to get along, the single kid really likes being with others? Any suggestions would be appreciated.
