Question for Hillfooter?

I can't help with the worming advice (I'm guessing you will be using Flubenvet?) But I can help explain how the breeder wormed them in a weekend.

There are lots of different worming products available and some are a single dose, either applied to the skin, added to the water, or given as an oral drench direct into the beak.  The breeder would have used one of those to worm them in the weekend - although most advice says to give a second dose 10 - 14 days later to get the worms at every part of their life cycle.

Can you get in touch with the breeder and ask what she wormed them with and whether they had a single dose or a follow-up dose too?
