Hi First, I love my chickens... I started keeping them last April and my current flock size is 12, with more ordered for April and August. Second, I love this site! Now down to business... I have not yet wormed my flock but from what I've gathered, should put them on a routine maintenance plan. I'm going the valbazen route with a syringe but have a few questions: 1) should I worm my two 7 week old chicks (one EE and one silkie), if so how much each, If not at what age and how much? 2) should I worm them annually or semi-annually? 3) should I use a different brand next time, and if so what kind? 4) if I use a different kind next, is it ok to just keep rotating the same two? Thanks in advance to those of you who will chime in.
