I have free range partridge rock roos, and they are about four month old. I weighed them today, and they only weigh 3 1/2 lbs! When I butchered their daddy he was a year old, and weighed 5 lbs dressed. Should I pen them and feed them meatbird feed the last few weeks? I feed them that free choice, but they never eat it. DH is afraid that they will get fatty and not develop any more mucsle if we do that. I am afraid they will get tough if we let them keep running free. Also, should I start confining my 2-month old roos now, so that they grow faster then these did?
