Greetings from Kansas, kkovacic, and

! Pleased you decided to take the plunge and get chickens and also glad you stopped at BYC! This is an awesome community that can help you every step of the way! First off - where to get chickens. In my neck of the woods, starting about February, local farm and ranch stores sell sexed and unsexed chicks. If those aren't available in your area, mail order is a great option. Chicks are amazingly resilient through the mail and the bigger outfits are very reputable. I will give you the names of large hatcheries I have ordered from in the past. These have done well by me and offer a great variety of birds from which to use. Murray McMurray....Meyer Hatchery....Cackle Hatchery....Stromberg's....Ideal Poultry. There are others but these are ones I can personally vouch for. If it was me, I'd pick the one nearest to PA. Anything that might cut a day off of shipping is a plus. I can almost assure the chicks will arrive in great shape. You can research/ask other hatchery opinions in this link:

Then when you get them it's just a matter of dunking their beaks so they figure out where the water is and show them their chick starter food as they go to town in their brooder. Some folks put electrolytes (available from wherever you order) in the water to give them a boost. But once have the chicks...actually before...check out the Learning Center here: it is a treasure trove of useful poultry information. Obviously, you will want to pay most attention to the raising baby chicks section. Here is the link:
