Monday i got 5 chicks from a local family who had ordered from a hatchery (I'm not sure what one) I brought the chicks home and Put them in a Plastic rubber maid bucket with pine woodshavings. The water bucket leaked so we had to replace with newspaper because we had just ran out of shavings... I used a 75watt bulb for day time and a 100 watt ceramic heat bulb at night. Today I went and picked up two more chicks from a Different person. I got home with those chicks at 8pm and put them in with the other chicks. Everyone seemed happy healthy drinking and eating. My boyfriend had changed the light to a 100 watt bulb and placed it about 14inches high above one corner of the bin with food and water on the other side with new bedding temporarily as newspaper some flat and some shredded up. I went upstairs to change the light to their night time bulb and thought they were all sleeping snuggled up together. Much to my dismay when they didnt wake up once i accidentally bumped the bucket I checked them.. 5/6 were dead... I am just at a complete Loss as to what could kill them in that amount of time? Less than 2hours.... I just dont understand. My boyfriend thinks it was too cold.. but with the bulbs i was using before he changed it to a 100 watt they were keeping the bin at 85. Did he cook them accidentally? They were a week Old chicks aracaunas, rhodeisland red, buff orpington, and a brown leghorn. I just dont know what went wrong. I have one aracauna left and I dont know wat to do please help or tell me what i did wrong?
