I have chicks that are a few weeks old and one that is about a week old. I have them on medicated starter and I clean the brooder frequently and give fresh water what seems like every hour! Where do I go from here. I have been reading about all the pests they can get. What can I do to safe guard them from pests and worms? Am I supposed to give them worm meds before they get them? Or only if they get them? Could they have them now even if they haven't been outside? I plan on using a river sand floor in my run and in the coop using the DLM. I also will use DE. What else can I do to make sure they don't get sick or bugs/worms? They will also have a larger fenced grassy run outside of the secure run/coop. Can I treat this area with something?
