I just got six baby chicks and we are headed home, i have everything i need for them but i am wondering if i need to add anything to their water? Like an antibiotic or duramycin or something like that? Here is a list of what i have already, let me know if i need anything else Brooder Pine shavings Chick feed Waterer and feeder Heat lamp And of course a coop for later! Please let me know soon and give dosing details and such. Four bantams and two pullets.
