If Jwhip is duplicating the cross that he did last year, I think most would be happy with the results. If you pushed them, you could get them processed with good weights at 12wks. I saw 14wks last spring and did not push them.It is great to have you here!
Oddly, two of the Breeds that have been the most productive for me are not form the United States. I wonder what happened?
Just regular 20% chick starter and throwing them some corn, mine were ready at 14wks. If I had raised them confined in a house and run, and fed them 24% -28% from hatch, I think that I could have got 12wks out of them. I am speaking of 3.5 or 3.75lbs dressed clean. No legs. LOL.
The pullets were laying decent sized eggs @ 20-22wks.
This performance is wat made the NH popular in it's time.
