We've been raising meat birds for 8 years. We've been around the block a time or two and seen and dealt with just about everything a chicken can throw our way. We have now met our match. Since there isn't much info I can find on Pioneer birds I thought I would share a bit about what we've learned in the last 4 week. The good- Growth rate has been faster than McMurray said. Pretty and varied feather colors. Feather out fast. Friendly but fast. The bad- Love to fly and learn quickly. This is a good or bad thing depending on your set up They are strong and often knock waterers over as well as feeders. Feed conversion is worse than listed on the internet. They are very stupid. They often forget where the waterer is located and will wander until you show them again. They do not follow the flock very well and so it's crazy chicken with it's head cut off type chaos in the coop all the time. High maintenance. Must be checked on every couple of hours because of behaviors listed below. They are very messy (much like the cx) and drench everything with poo. The very, very ugly- These birds have proven to be insanely cannibalistic. So far NOTHING has worked and they have know killed 10 (an order of 20 started this mess). These are not pretty killings, no, these are waking up to internal organs everywhere. They are so strong/heavy that they can easily smash another bird in a few short minutes. They need about 5x the amount of space as regular chicks of the same age. In all I would not recommend these birds unless you have a very large free range system set up. They are not for the faint of heart or for kids to take care of. They are high maintenance in a way no other breed has been thus far. While their growth has been quick their feed conversion isn't good. If you want to raise meat birds I'd say choose another breed. All that said, if you've had good results with this breed, I'd love to hear what your experience was.
