I've had chickens off and on (mostly on) since I was in my 20's. I'm 71 now. I can't remember what I started with, probably RI Reds. The most I have had is 40! That was a lot of chickens!! I started selling eggs to help pay for the feed. I have quite a following and people swear, mine are...
A couple of chicken lovers stated that they would like to print the chart, but could not. I just printed it. Just use Ctrl P, pick the pages you want to print. I printed pages 3-5 and it worked fine.
