Hi all! Question time!
I have a budgie named Toodles (1.5 years) and a baby cockatiel named Popcorn (6 months).
tl;dr: Toodles absolutely adores Popcorn, but Popcorn has wants nothing to do with him, and she (I think it's a "she") tries to bite him.
Popcorn by herself is very sweet, loves scritches and walking around the apartment, climbing on shoulders, and seems as pleasant as can I could ever ask for in a very young cockatiel. Toodles is also an incredibly sweet, free-flighted, albeit high energy bird, and loves to talk to the cockatiel while she is in her cage. However, when both are out at the same time, any time Toodles gets close to Popcorn, Popcorn will open her beak and try to lunge/bite Toodles. Of course, the budgie is always quick enough to avoid being bitten and seemingly oblivious of her hatred, because he doesn't stop talking to her and trying to groom her, but I don't like this interaction regardless.
Is this a normal behaviour? Will it go away? I was always under the impression cockatiels and budgies got along well, and if anything, the cockatiel would annoy the budgie, but this seems to be the opposite. What should/can I do to help them bond, or will it just take time?
