This is the first year that I've really let them sit and hatch, so I don't really have an average to speak of. Two of the three chicks I lost were still with moms. One was with the brahma, and both chicks get pretty far away from her so I imagine she was too slow to do anything about it. Maybe she was on the wrong side of the fence. I just don't know. The other one could've been left outside by the hen, as I'd shooed the chick back into the coop when mom left it outside three different times (she had two)

I've since taken her other one away and put it with the chicks I got from the hatchery. Out of the five that were hatched in May, four made it to weaning and are still alive. I wish I could tell you what happened to that one, but

Cat, more than likely.
