Syringes (for flexible tubes) these have standard fittings to connect onto the flexible feeding tubes. The large 35 and 60ml syringes have a special 'catheter' tip which fits the large flexible tube
Sadly the 6ml oral doser syringes are no longer available
The small tipped syringes are ideal for worming birds, administering Critical Care Formula and fluids. While the catheter tipped syringes are suitable for handrearing.
