This is my 2nd year with cornish X's. Last year went well but this batch has me stumped. They will be 8 wks 5/12 but in the last 2 days have found 3 dead for no apparent reason. Anyone else having problems or suggestions to do? They are fed all stock sweet which is what we fed last year & had no problems along with table scraps. This worked really well last year & produced some very tasty, tender meat. They didn't show signs of being weak or anything so I'm stumped.
