I have been raising my cornish their entire life...4-5 weeks....in with the layers. They are completely different looking from the cornish I have helped my buddy raise before at this age and from what I have seen online. These cornish are behaving/growing more like freedom rangers. They are getting a choice between 16% feed and 20% usually almost 99.9% of the time eating the 20%. And get to be outside as much as they want and run the whole chicken yard. They are still very active and have strong legs. I'm hoping though just like a freedom ranger they will continue to grow even though they are given soo much room to excericise and such. I will have to get pics of them tomorrow...they are from TSC and they get them from Mt.Healthy in Ohio. Pics to come tomorrow!
