Well I got my shipment of 25 Cornish Cross Pullets from Murray two weeks ago and I must say these things are amazing! I also got 25 Red Stars along with them. I have raised several birds in the past just never Cornish X. I am reading about how fast these birds grow and am amazed. My questions are this about the meat birds.... 1) How long do I feed start & grow? 2) What do I feed after the start & grow? 3) How long do I have to have them under the light? 4) What is the average kill age for the pullets? Thank you so Much for any help with this adventure.
