I am having problem after problem with these stupid broilers. I am absolutely never buying them again! First they were trampling each other to death, then they were picking at each other to death and eating each other, now they are dying for no apparent reason. I'm losing an average of a bird a day. At this rate, there will be none left by butcher time. They are 6 weeks old. I intended to slow them down some by allowing them to run around outside and strengthen their legs and hearts that way, but they are REALLY small...1/2 a pound at most now, really not any bigger than some of my regular chickens would be at that age. I fill their feeders with Purina Flock Raiser (20% protein, no one here is selling broiler feeds or chick starter) which they are allowed to eat as much of as they like. They don't eat a lot of it, they seem to do a good job eating off the land, they always go in at night with full crops. They also have free access to brewery spent grains, which they love, they eat a lot of it. (25% protein) I went through a week or so where there were no problems, and I thought things were going to be better. And now they are dying again. I will find one hunched up with its wings limp and its feathers fluffed, usually standing next to food or water but not partaking of either. It feels cool/cold to the touch, so I will get it under a heat lamp right away. It will slowly become more limp and unresponsive, then stretch its legs out straight, throw its head back, and die suddenly. The whole ordeal takes just a few hours. I've seen them die from heart problems, and this is different from that. The symptomatic ones also seem sort of wasted away and skinny, (when just a few hours before, that same bird was fat and running around at full speed) and have empty crops. I use an eyedropper to give them some warm water and honey since they have no interest in either food or water (certainly not normal for these birds!) but it doesn't seem to help, they just let it run out of their mouths without swallowing, or if they do swallow it, they still go downhill and die anyway. The only thing unusual that has happened lately is that a couple of times in the last two weeks, the whole flock, Cornish as well as layers, have gotten into a pan of livestock salt (salt only, no minerals) in the goat pen and eaten some of it. I don't know why they suddenly did that, it's been there a long time and they always leave it alone, then suddenly they started eating it. Could this be the problem? If so, is there anything I can do, or will they all just die from it? I have gotten the salt out of their reach, so it won't be a problem in the future.
