I have two chicks in a good sized brooder (1.5 sq ft per chick) they love each other . My family already planned an overnight outing before we got the chicks. If I got a nipple waterer and provided enough food, would they be ok for one whole day? I plan to completely change all the bedding before we leave. They are inside the house and the heat lamp is good where it is-they are comfortable. Thanks in advance for any advice!
