Is it 5g/kg of what the bird weighs, or 5 g/kg of bird feed? I'm not helping, I'm probably just muddying the waters.
@ChickenCanoe, can you help, or do you know who is knowledgeable about exotics? I know you're one of the best when it comes to chickens ...
Hm. These are confusing instructions! Remove unmedicated water ... but unless your bird is one of those listed,* there are no instructions for medicating the water, only for medicating the feed. That's what I'm seeing anyway. What kind of bird is it?
ETA: * Parrot, finch or pigeon
