We got a male lovebird around 1 1/2 years old about 2 weeks ago and then got a 3 month old female lovebird for him.We put a tissue box in their cage (for housing) and the 3 month old female is shredding the sides and bottom of the tissue box and is making bedding,we gave her toilet paper and she has dragged it all into her tissue box.Shes in there all the time sleeping in it and shredding it, the lady i got her from said she is 3 months old. She can fly and doesnt have any black on her beak.She is smaller and still is growing her feathers.BUT SHES ONLY 3 MONTHS OLD!!! why does she keep going into the nest box,why is she making bedding,is she 3 months or older? This is my first experience with lovebirds, please help.
