We got our lil baby piggy a friend over the weekend. Our baby...nibbles..is only 6 weeks old. The new one...munchie...will be 2 in July. It seems like munchie is taking over the cage. When nibbles is eating munch will come and kinda bump her n the butt til she moves. We have 2 of everything. We will hear the pigeon sound and like a high pitched noise coming from the cage a lot. And I see my nibbles running away. Nibbles used to love lap time and us picking her up and now she runs from us and when we do get her she does a lil screaming sound and doesn't want to be petted is this normal or not? I'm trying to give it some time but I'm worried about nibbles. Not sure if age has anything to do with it or what. They are both girl btw. Thanks for any info you can provide.
