I have 10 week olds that have been doing great up until about a week ago. They're water was inadvertently off for three days, and lost one due to that. Since then they were doing fine when three days ago I saw one laying a bit on its side and looking lethargic. I took him out and brought him home, but since then he hasn't walked but will eat and drink. The next day another was looking the same so I brought that one home, too. That one can stand a little but is obviously weak. Today a third was easily caught so I took that one out too from the pen. That one appears okay, just a little weak. It's hot down here ( just outside of houston and its been around 95) but they have a covered area that I added a fan to help cool them off. Any ideas? I think the first one will be gone soon, but anything suggestions to keep the others going would be greatly appreciated. They're on a turkey starter and are transitioning to a grower.
