Even at this age?
Ive never wormed so young. Shes about 6 weeks.
chicks need to be wormed too . they eat all sort of stuff when you not watching .
organic Apple Cider vinegar is very good for them for over all health . I start mine #3 weeks of age .
wormed them ones a month .mine are free ranging ,so they get them selves into trouble by eating what ever they can find .
