Hi there - I wrote a nice reply and pressed the wrong button

07 But anyway here goes again
First I shall be interested to hear what everyone else does, but this is my method
I keep my own strain of dual purpose utility Marans. The girls are kept for layers which can be sold if there is a surplus and the boys are kept for eating. They normally reach 5 to 5 1/2 lbs dressed weight in around 24 to 30 weeks
I keep all the youngsters together and feed on chick started to about 6-8 weeks. Then split off the boys into their own stable and once they know it as home they are allowed free range of my large woodland garden (about 1 acre), where they can find plenty of insects, grubs and greenery, and just fed wheat morning and evening (that is the cheapest feed I can get from a local farmer)
When they are up to size they are penned in the stable for
around 1 week to maybe 10 days and fed boiled wheat and rice (put in Aga oven overnight) The feed is put down morning and evening, and taken away after 30 mins if they haven't eaten it all. If they have they get a larger serving next time
They have constant access to clean fresh water seaweed meal and grit.
This produces a fat free and delicious bird. It is not as pappy as the 7 wk old supermarket youngsters, but the flavour and texture are truly excellent
All the best
Sue
