Got a batch of 100 on thurs. Have them set up with two lamps and 2 waterers. As soon as they got out of the box they started drowning themselves in water. Now they aren't fluffy anymore but they are dry and at 90 degrees but are still dying. They are in a brooder with wire floor. Have lost 30 so far and they are still dying. We used the same set up a last year and never had a problem b4. Is it the humidity? Help please!
