Thank you for all of the advice. I appreciate it more than you know. I did worm them, but, yes...... I did...... I put it in the water. I'll go ahead and worm each one individually. I'll send before and after pics of the roosters legs in a few days. You won't believe the difference. :)
(1) Are you new to chickens / when did you first get chickens?
Yes, we are very new. We took over the neighbors flock around Thanksgiving 2014. Some of the chickens are quite old and we knew that because the neighbor told us they were.
(2) How many chickens do you have right now?
13...
