I have ixworths, which i would recommend, they lay a good few eggs and are good chunky meat birds. I did have two sasso cocks which grew quickly, but alas you would have to ask the badger what the meat was like. I was going to use the sasso boys to cross with the ixy girls for a meatier bird, but that has been sabotaged by mister brock for now. Due to the excessive onslaught of badger attacks I am downsizing my poultry as whatever I do I cannot make the freeranging area safe for them, without a lot of cost. So I will have a smaller flock of birds in a more secure run. Fewer egg layers and a few dual purpose ixworths. Light sussex were always a good dual purpose bird also. There are specific meat breeds which bulk up quicker, sasso and ross cobbs seem common. Also some more traditional breeds such as the ixworth and Indian game( sometimes called cornish) The bigger breeds of birds like the sussex, rhode island reds,Dorking and plymouth rock are classed as dual purpose.It's usually a case of whatever you can get hold of that takes your fancy.
