I have a older lovie that I got from someone who is very timed and I recently bought a young one from the pet store who is about 1 year old now. I keep them in separate cages but every now and then I let them out and they seem to get along just fine, the older one feeds and grooms the young one. Is it bad to let them out every now and then and then separate them, they are always next to each other in there cages.
