A friend of mine brought me some wild native chicks that he caught today. They look like they were just born, all fluff as no feathering as started yet. I am almost sure that they have some kind of "bugs" as he caught them very close to a land fill, aka garbage dump. What I would like to know is what is the earliest that I can deworm them and/or dust with Damascus dust or seven dust? (I have some Welsummer chicks now that are just over 2 weeks and may deworm them the same time.) Any advice on this matter would be greatly appreciated! Thank you!
