so glad you joined us. Good luck selecting and raising your own flock.
Your experiences with injured chickens goes a long way in helping you plan to avoid that for your own chickens. Access to a vet who is even willing to treat them at all is an ideal situation. Many of us have only BYC to help in case of problems.
There's quite a lot of helpful information on this site to help you get started, if you haven't already done so, explore the Learning Center Articles.
Have fun raising the baby chicks, I know you will find it a rewarding adventure.
Welcome to BYC! Raising chickens is pretty easy. A lot is learn as you go. I grew up watching my mom take care of them so I have a pretty good idea of what is going on. I just got my own last year and so far so good. If my chickens survived the winter of 2014/15 in New England then I think they can survive dying. lolol
