I guess I should have done more research before letting my local Tractor Supply lady talk me into buying Cornish rocks along with my Bantams. ( I had only planned on buying bantams but Tractor supply requires you to buy at least 6 chicks at a time. Since there were only 3 bantams, i had to pick 3 of another breed) From what I have read, I guess Cornish rocks are meat birds. I originally started looking on BYC to see if they were just lazy birds.. Mine sit all the time, Rarely stay standing for any long period of time. I am assuming this is because they grow so fast and are to heavy for their legs?? What are their life expectancies? When , if I can bring myself to letting my husband kill them, is the best age to do so? I have seen mixed opinions on this.. Thanks for any info you all can give me ..
