Hello , I am a newbie to chicken raising! So new I don't even have chickens yet! So here is my story: After hurricane Katrina, someones flock (of maybe 6-8 birds) ended up seeking refuge in a wooded area on my aunts property. Four and a half years later, there are now about 20-25 birds in that area. I mentioned to my aunt that I wanted to raise chickens for egg laying starting this spring...and she suggested I come to her place and get as many hens as I want. I really want to start out with pullets but since I'm so excited about this new adventure I thought I might try these "wild" birds first. What shoud my concerns be? Health; as I don't want to contaminate my coop (if that's even possible). Chickens that are very mean won't be much fun. I just thought I might "try before I buy" and see how things go. Any advice?
