I am new to the forum and to meat birds. I bought 6 five-day-old Cornish Rocks from
TSC February 23. I have been feeding mine a Chick Starter/Grower from Bartlett Mills:

. It contains a botanical supplement called APEX (
http://www.bartlettmillingfeed.com/images/apex poultry.pdf ) and no antibiotics or animal products. I fed them free choice for 4 weeks, then when I moved them from the brooder to a converted horse stall pen, I have been feeding them all they want during the day, and there is still a small amount of food in the feeder in the evenings. However they run out sometime during the night/early morning, so they do experience a little hunger during the night. I haven't had any leg problems, and these guys are HUGE! They turned 8 weeks old this past weekend, and I know a couple of the roos weighs 10 pounds. I just found out that they have a specific meat grower/finisher pellet, so I am going to call my feed store to find out if they can get that for me.
I haven't had any leg problems with these guys. The have their awkward gait, but run around, flapping their wings, and seem to be very healthy. I am not set up to let them out right now, but their 12X12
I have a second group of Cornish Rocks that are 4 weeks old, and they are thriving as well.
I will most likely harvest my first birds this weekend or next(9-10weeks) and will let you know how they process out weight-wise.
