I've read the learning sections for new chicks etc but I still have questions. I've lost 3 chickens and need to replace them but can't find the kind I want anywhere around here so I will have to end up ordering them from a hatchery. 1.) How do you control the temperature if you don't have a heat lamp? ermmm thats kinda all the questions I have at the moment but I'm sure there are going to be more to come.
