I will build the door tomorrow and run the wire. I have at least 9 more of these to make. 3 will be dedicated to FD's cornish. 3 for the midget White turkeys, and 3 for selective breeding of my other birds.
One of the main obstacles I faced with my CX was not having my pens set up to where I could KEEP the breeds separated. Depending on type and purpose I manage the birds differently. Some folks probably feed their entire flock high protein continuously. I only feed the game birds and meat birds the high dollar stuff.
