best breed for eating

we tried Ross cobbs and quite frankly we were a bit disappointed, they weren't much to shout about regarding taste considering they fully free ranged, in fact we didn't even bother eating the last 2 and a year on they're still pottering around in the garden

thx for all these replys its very helpful and i have enough room for about 8-10 birds but do not want cocks because the neighbours and i think the dual purpose aint essential as i have 3 warrens that are still laying
