I've been reading a lot and you have to keep them in separate air spaces.... right now, the first batch is in the house. The second batch is also going to be in the house. The first batch is in the living room in the new, bigger brooder. The second batch will be in my craft room in the storage tote that the first batch started out in. The first batch should be ok in the new brooder until we are ready to move them into the coop, then batch 2 can go to the big brooder. But with them both being in the house, they aren't going to be quarantined the way they are supposed to be. So, now what?
