I work from home, so I have the brooder set up in my office so I can keep an eye on my 2 chicks during the day. I also let them out to play for a good part of the day. Whenever I leave the room, even for just a few minutes, they cry like they're being tortured. As soon as they see me come back or hear my voice they settle down. They also follow me around the room so closely that I have to be careful that I don't step on them. Is this normal? Am I spending too much time with them?
