A local hatchery here has Red Star Rangers (slow growing broilers). I am trying them for my next meat batch, because the guy that breeds and hatches them says that they breed true.. I am really excited to give these a shot.. I want a sustainable flock that isn't as slow growing as some of the heritage breeds.. My cornish X are 4 1/2wks old and fatter and fatter everyday.. I am excited to compare the cost of being able to breed these Red Star Rangers and allowing them to free range vs. Cornish X.. I will keep all of you posted on the progress...
