I am looking at getting these cornish chickens for meat birds in the spring: http://www.welphatchery.com/cornish_rock.asp I was thinking 2 runs. The first 25 chicks, then if it goes good, 100 chicks Now I hear things like you loose 1/3 before butchering. Is that right? Is it that high? So out of my first 25 chicks, only 16 would make it to the table? Now Welp says to restrict feed daily - to only feed them from 7am-7pm to cut down on flip, but can I still expect to loose 1/3?
