out of my 11 tiels 4 of them bieng babies I can only touch one this includes stepping up her sitting on my shoulder, preening my hair, giving me kisses, the rest run or fly from me, hiss at me, peck at me, or down right bite me........ I do not want to sell any of them just because they're not tame. and only having the bird 5 days is in no way shape or form enough time for the bird to earn your trust. it takes patience, I've had most of these tiels for a year and still can't come near them, I can't get near any of my budgies w/out them flying off had the majority of them for a year . it doesn't bother me one bit that none of them are tame. I like sitting in the bird room and watching them fly around, and interact with eachother and listen to them chirp and sing to each other - that makes my day a whole lot better.
some birds take a while to adapt and earn trust, you can't give up just because your afraid to be bitten. I've been bitten more times then I can count, from budgies, to tiels to a Quaker who hates me with a passion - he does everything in his power to attack me I've had him one year since July 17th, and I have no intentions in giving him up. even know he hates me dearly. he's pierced my boob for crying out loud! that ain't love!
Give the bird time, with time, and patience comes a tame bird.
