We have one week old baby chicks and we are keeping them in a kennel for the time being... good ventilation, wire so the heat lamp doesn't catch anything on fire, easy to clean... good idea! NOT!!! Today, the chicks have disovered that they fit through the slots and the chicks go in and the chicks go out. We chased them for a bit and then worked on a solution. If they don't get their act together, they may become chicken stew instead of egg layers!!!
