Happy Easter from the San Fernando Valley, in Southern California. We are getting our very first checks in a few days. I have madly reading everything I can finding on the Internet. I have a few questions: 1. We are picking up our day-old checks at a hatchery. To get the breeds we want, we would need to pick some up one week, and the rest a week later. Question: is the week's age difference important, or should we change our choice of breeds so they are the same age. 2. Regarding raising them outside in a brooding box like the ones I read about at this website..we have daytime temps in the mid-70's here. Can the chicks run around in the enclosure now (under supervision). 3. Any other advice for us?
