Just got in a batch of broilers on Monday. In the last four days, we've lost 7 chicks. Everyone seems fine. Temp is good. Plenty of food and water. They are eating and drinking well. They are moving around great. Every now and then one will get knocked over by another. It will fall on it's back and not be able to flip back over. Then it just lays there. If I don't notice soon enough, it seems to suffocate. I've seen it happen a few times and flipped them back over. Then they get up and run around as if nothing ever happened. They'll usually go get food, water, or under the lamp, but I would expect them to do that if they've just spent the last who knows how long flipped on their backs. I've never seen a batch of chicks do this. It's like they aren't strong enough to flip back over. They aren't falling over for any other reason that I've seen other than being knocked over by another passing chick. They literally look fine on minute, flipped over the next, then dead a while later. They get electrolytes and grower feed, btw. Anyone have any ideas on what to do? Is this a bad batch? They are Murray McMurray.
