Well, it finally happened. Lost my first bird under mysterious circumstances a couple days ago. Not sure what got her. My 12 mixed flock layers I got as chicks last August. They free range every day but are locked up tight at night. I have lost two meat chickens to this unbearable heat but this is the first hen. Interestingly, I also have some little pullets, 12 Cornish X and 5 ducks running around that were born in May of this year and I still have all of them plus the meat chickens I mentioned. But my Black Australorp hen didn't show up one evening. I thought maybe she was being broody somewhere but my search turned up nothing. I guess I shouldn't complain too much - just one chicken in about a year isn't too bad. I read on here about entire flocks wiped out by predators. That would be rough! Happened in the daylight hours, no sign at all - just gone, and nothing missing since. So, any ideas?
