Hi guys, new to forum thing. I have two 6 month old isa Browns and yesterday when my son picked one up I noticed she threw up quite a lot for the first time, she then layed under the trailer for the arvo which I thought was strange cause usually she is wondering around the yard, this morning when I woke she was dead in her coop this is our first time it's chickens so any idea of the cause of death? Not visible signs of injury and from what I can see poos were normal. We do have the odd cane toad here so wondering if she may have pecked at it? Other chook is a bit distressed but seems healthy.
