I have a feeling Castle Farm keeps Jersey Giants, but whether he has any hatching eggs at present I am not sure, but if not now he will probably have some before too long.
I keep the English Cuckoo Marans, and I find them lovely birds to keep. They are slower growing, but make about 2-2.5 kilos dressed weight in about 24-30 weeks. I feed mine chick/growers at first, then once they are strong enough they get total free range and unlimited straight wheat
10-14 days before killing they are penned in a quiet place and fed boiled/soaked wheat/pear/barley. Cleansed for 24 hours plucked then hung for 2-3 days before dressing depending on weather.
I find them an excellent flavour and texture - a real gourmet treat, and with the advantage that any female chicks can be kept for their lovely eggs, or sold on as growers or POL for which there seems to be a ready demand.
