Helen W. is unsure about her two birds:
Love bird and pineapple parrot.
They are a pair.
The pineapple parrot likes to bite me.
The love bird attacks her fruit treats.
“Birds of a Feather, Stick Together” And you have no feathers.
You say they are a “pair”?
They likely have bonded and are not likely to ever let you in unless you were there from the beginning.
I’m guessing the “pineapple” is a pineapple Green Cheek conure?
You may have some luck if you can separate them and bring one at a time into another room to work with.
Only time and patience can tell.
You may have better luck with a “single” older bird.
