cheers mate i get my syringes off a dairy farmer,they contain orbeseal,dry cow intramammary infusion,once hes used em he gives em to me,i find them ideal as the ends are very small,you can see the end of it in one o the pics and i use nutribird a21 by versele-laga,they use it to handrear parrots but itl do any bird, the feeding times vary,it depends what im doing,sometimes they can get 4 feeds in an hr and sometimes they might get one,2 or 3
