Most will worm twice a year spring and fall, if you wait until you see the worms in the poo, they will generally have a bad case of it.. I worm mine as a preventative twice a year, I personally use Valbezan, mainly beacause it is what my dogs also get for worming. It will not hurt the birds and if they are wormy it will actually make them healthier.
