I must say, that when maybe you buy from a breeder that handrears lovebirds/parrotlets, which don't often happen it would make a great pet

. One of my very good friends got a baby lovebird from a lady who did'nt want to handrear it any longer, and he handreared it himself. It was a blue one and as tame as can be, its like a big parrot in a small, goodlooking package. He/she was soo cute, never bit and had full flight of the house.
But i do think when acquiring a lovebird/parrotlet, it should be handreared, that beak can surely bite very, very hard. I'd say, when acquiring a pet bird vs aviary bird, the pet would definitely require attention from his humans because he is infact now part of the family being handraised by his "mom". Where as aviary birds, yes people do try and make their cages look natural, but the most important thing is that the bird was raised with is own kind and will be associated with them as such.
There are'nt any toys in nature so they keep eachother preoccupied- chasing, grooming, and playing. So throwing in some chewable wood, is more than enough to atleast keep their minds off being in a cage.
But as many people sometimes just want to make money:53: out of the business, they try and throw in as much breeding birds as possible. Which is sad indeed!

. O and one other thing- Budgies are infact parakeets, where parrotlets are small parrots.
Just my opinion, dont know if it makes any sense!
