No. Just regular cheeping.
But also, to clear things up a smidge, I'm talking about guinea keets, not chicks. At this age there's not much difference. They just want warmth, food, and water. But the keets are noticeably more skittish, and seemingly WAY more fragile.
I went down a few minutes ago and it seems like they might be getting it. 6 were underneath, and 5 were where the lamp was strongest. I have faith that they'll get it. But I've already lost several keets in the first week when I've NEVER had a problem with chicks (though it seems to be under control now as no keets have died in the last 48+ hours), so I'm paranoid and itchy to make sure they all find the heat and use it before I lose more.
