my lovebird has broken of about of an 8th of it's lower beak,i havn't noticed any blood however i need to know if this will grow back , the best way to feed her, & how long this regrowth will take

Yes birds beaks do grow back so don't worry!!! the best way to feed this bird would be like how its always eats unless its having problems.

A birds beak grows about 1-3 inches a year so lets hope for the best!

Best f luck to your fine feathered friend!
