First timer here! I'm picking up my chicks tomorrow at a feed store close to my job so the babies will be hanging out with me at work. I have a meeting in the afternoon at a different location (about 15 min from the office) then will be heading home for the 1 hour commute. I've bought some handwarmers for the ride home. Is it OK to keep them in the box from the feed store for the day? Or should I lug the brooder to work with me? I'm also wondering if I should take them to the meeting with me? Will they be OK without food and water for 3 hours while I'm at the meeting/driving?
