We raise about 500 broilers per year (~350 Jumbo Cornish from MMM and ~150 Freedom Rangers). Took delivery of current batch of 90 males about two weeks ago. Since then we have lost 30%. Had the usual couple of DOA's and a few more on Day 2, but we continue to lose 2 to 5 birds per day ever since. My brooder setup is the same I've always used (4x8 box inside a secured barn), fresh crumbles from my usual place, plenty of water w- Broiler Booster, three infrared lamps; really, nothing different from how I've always cared for them. For some reason these birds were sent Priority Mail rather than Urgent Mail, so they spent an extra day in transit - but I would think they would've recovered from that fairly quickly. I usually count on 10% mortality with the CX's but waking up to find what were healthy birds now look like they were run over by a truck every morning is starting to get to me. Has anyone else had similar experience with recent deliveries from MMM? Thanks.
