Hi, I've had both. I've raised lovebirds and hand fed the babies.
Georgie is a female and is awesome - females that are nice - are NOT the norm. Males are easier going. Georgie is DNA sexed and is a girl. She comes/flies to my shoulder when called. Does not speak English - but does "talk" to me. She is a normal peach faced loved bird with a little bit of yellow on her lower tummy. He best friend, other than me, is a black capped conure...they cuddle, eat together and sleep together. She has access to another female love bird but, likes Libby, the conure better. I would look for a baby that still has a dark beak...that has been hand fed. I would ask that the breeder/seller have the baby DNA sexed. It'll cost a little more - but, it'll be worth it. Female lovebirds, as well as other female parrots & parakeets can become cronic egg layers...this can become a health issue down the line.
I've also had a Quaker Parakeet. Ozzie was male...and not your normal Quaker. Quakers can easily become cage bound...they don't really want to come to you or out of their cage. Or, they guard their cage and become agressive to anyone that attempts to clean the cage or even stand by it. They can also make a lot of noise! I would only recommend having one if you OWN your own home... and not live in an apartment. Ozzie was a really good talker and was always gentle with/to me. I have two sons, both were much younger then...and Ozzie was very good with both of them. Keep in mind however, these kids grew up with a lot of birds...and were not easily bullied by any of the birds. They had a pretty decent understanding of how to care for a bird and how to handle them. Some Quakers do become hormonal. Also, a previous poster is correct - they are illegal in some states and being "watched" in others.
A sexed lovebird might be the best choice for you - even if you have to pay to have it DNA sexed - which BTW is safe. Let us know what you decide. Remember, it's important to have the baby lovebird have black on its beak. Some babies within the "clutch"
(family) have more than others. But they should all have some on each side of their beaks and at the tip. Good Luck & have fun!
