They need a lot of care, esp in the beginning. We got chick in March and for the first several months they needed to be checked, fed, water dish cleaned, temp monitored frequently. Their pen needs cleaned frequently. If you're getting different kinds of birds you'll either need to keep them separated by breed to ensure the breeds don't cross. If you don't have the space for something like that then you might want to focus on one breed and expand once you have that one settled in. My boys have been mating my girls since June and we have fertilized eggs. We got our chicks in March so you will have about 3 months where you can have them all together. You could keep your cockerels separate and put them w/ their same breed females periodically for mating, but you'd still need 2 separate homes for the 2 sexes. If you're looking into incubating eggs I would invest in a good quality incubator and read up on the process. I've read a lot of post here from novices and seasoned hatchers alike having issues where they lose entire sets of eggs. I haven't hatched eggs so I'm not sure if there's a waiting period after they start laying to ensure better quality / viability. There's a lot of resources you can look into about hatching. Also, look around in your area to see if there are any vets who deal with chickens. If you're going to be serious about breeding it's good to know about that ahead of time for emergencies and illnesses. One sick bird can wipe out a whole flock. Good luck! I hope your adventure works out for you.
