When I was picking up the first batch of birds, the feed store convinced me to use to gamebird feed to avoid medicated chick starter and as they said have fewer leg problems. (Of course, they also said to butcher right at 8 weeks and not a minute longer). I didn't even know this forum existed then. Like I said I've raised DP breeds off and on for many years, only probs I ever had were of the predator kind. I did pick up two different batches from two different feed stores. The second batch were a few days younger, now I'm beginning to wonder if I'm just losing chicks from one batch. Which makes me wonder are there different varieties or qualities of Cornish X? There seems to be alot of mystery about where they come from. Is the cheapest cornish X just as good as the most spendy? Do all the hatcheries get eggs from one monsanto type breeder or are they each breeding their own version?
