Thanks. I do have them in two separate brooder boxes each at the far end of the house- as far away as I can get them. I am a nurse, so I realize the details of quarantine. I tend the outside grown chickens, then come in and take off my shoes, wash my arms up to the elbows and tend the little chickens (from the hatchery). I wash to the elbows again, change clothes (usually to a mumu) and tend the new chicks. then, I usually go take my shower. I will stop and get Nutri Drench today to start them on and try to figure how much they eat daily(there is a lot of spillage with dry feed) to start the fermenting process. My grown hens get fermented feed- I was just nervous about starting chicks on it.
