For the last 2 days some of our Jumbo Cornish X from MMH have started attacking our rubber boots or trying to peck us. They are 4 weeks old tomorrow. I told my DH I am going to keep a permanent marker in the barn and start marking them #1, #2, etc. as to who is first in the slaughter line!! This is the first time that we have raised broilers. Just curious if anyone else has experienced this with this breed. They are all roosters too so I am sure that is probably part of it. At least we can outrun them !
