There are 4 and 5 week old babies in one pen that were fine, 2 month old babies in another pen and they are fine. And 4 month old chickens in the 4th pen, all fine.
I've never seen so many dead babies spread out like that. No blood. They were fine at 7 pm, when I shut them in for the night. I have tenants in a second house on the property that is closer to the chicken coop. They said they heard loud chirping around 2 am, but didn't go investigate. I'm wishing they had....
I am still thinking about this...Please do not think I am being critical. That is not the case, I am trying to figure out why they died. What we need to do is figure out why they died so it never happens again.
10 day old chicks or even new babies, should not die of cold in southern California in one night. How cold did it get? They were not even outside they were on a porch.
While the concrete floor could absorb heat from them. I assume there was bedding that should have mitigated that.
Did you have a light over the heat source. I always use a ready lamp, one of those you get at Barnes and Nobles that clamp onto a book as you read it over the heat source. It is not enough light to keep them awake but enough to keep them near the heat source.
I find the deaths confusing, we ship day old chicks up here in the north in below freezing temps and they live. Granted they are 15 to a box and it is a tight area, but the boxes have holes and it is pretty darn cold in those trucks.
By New babies how old are you talking 24 hours or less?
Sorry if this is not very orderly written, I am trying to think about the "why" as I type.
