I wormed both of my flocks last night - the adult flock because it was time for their yearly worming and the juvenile flock because I had some concerns about gapeworm. I use valbazen (albendazole) to worm. We do the wormings at night because I've found that to be easiest. Just pick them up off the roost, dose them and return them to the roost. The two sets of birds that we didn't worm last night were my two silkies and the meat birds. I plan to do them today, but now I'm having doubts about worming the silkies. They are so tiny! So my question is twofold. Is it safe to worm tiny silkies? (I don't know their actual weight, but could do that today) And, is it okay not to worm them when the rest of the flock is being wormed? I don't want the silkies to re-infest the others if they do indeed have gapeworms. I'm not seeing any evidence of worms in the silkies.
