Taming Robs - any tips ?

[Joanna]

Could you provide me with a few tips of taming my Robos ??



I have 4 girls and 4 boys and I put them in same sex pairs in separate cages. One is always more brave than the other. When I put seeds in my hand, they would come to bite on my hand first (make sure my hand is completely dead...I suppose) before they would sit on my hand to pick the seeds.



How can I stop the biting ?



The two older boys had a fight with the 2 younger boys and drew blood, therefore I put the two pairs in separate cages. Could I try to put them together again ? They are 3 weeks apart from the same parents.



Thanks/Joanna
