Yesterday was a tramatic day for us. After losing 7 of our brand new babies, I came home in the afternoon after running errands and found all 4 of my 10wk old chicks laying in their brooder cage dead. Those were my first chicks and I have been very protective and watchful of them. I have no idea what could have happened and was wondering if anyone had any ideas. Their cage is inside my other chicken pen but they are off the ground and away from the other chickens. They did get down on the ground for a few min while I cleaned their stuff and gave them new water and food the day before. But they have been down on ground before. They ate some cracked corn that the older chickens had left and there may have been a few layer pellets still there but not many if so. They were healthy and always flapping and trying to fly around then they were gone. Any suggestions and opinions would be appreciated. I just don't want it to happen again. They did seem to have scratched their face with their toenails due to gnats starting to come out. But it just happened and wasn't bad. Which leads to the question.. Does anyone know something safe to put around them or on them to help with gnats? They are horrible around my black hens.
