I am new to the world of guinea pigs. I got two little girls almost 3 weeks ago and got another one two days ago. She is an English crested and I had no idea she was so young. Brownie (like the treat ) is a sweetheart about Lady trying to nurse on her, but sometimes she gets annoyed and runs from the open area portion of the cage (12 square feet with plans to build a bigger one) and hides from Lady. Then Lady wanders around looking frantically through everything wheeking softly trying to find Brownie. She willingly takes vegetables and fruits and drinks water and eats hay and pellets, but I am concerned and it is heartbreaking to see her try to nurse on another Piggie not too much older than herself. Is there anything I can do?
