Hi, This is my first time with broilers. I have 50 that are 2 weeks old. We have them in a big wooden box roughly 6'x3' with a chicken wire roof. I have two 100 watt bulbs and a thermostat set at 80. We have fortunately only lost 1 so far within a couple of days of arrival-don't have a clue why but anyways-I have noticed a couple of my birds (6-8) have started sneezing. I have a blanket underneath the box so the cold of the concrete floor doesn't wick up through the shavings and a blanket on half the top to keep the heat in. I'm keeping plenty of shavings in there with constant food and water. It also stays roughly 50 in the garage as we have a split and it's under our bedrooms. Has anyone heard of chickens sneezing and if so do they have a cold or something? Should I be concerned and if so, what should I do? Should I take them out and keep them seperate so as to not spread this? Any help would be great-Thanks!
