I have 15 - - - 5 week old chicks. We have had them for 2 weeks. They spent the first week in the house while we but their outside hutch / cage. The hutch area is heated with a heat lamp. We monitor the temperature and keep it around 60 - 70 degrees. Considering the lows have been in the 20 - 30 degree range - - - we are doing the best we can. They are not showing any signs of cold. They are little live wires running and jumping all the time. We they settle down, they sleep in a pack - - - - beside each other but not on top of each other. They have a run area attached. The water and food is kept in the run. So they have to step out in the cold to get the food and water. OK - the problem is SOME OF THE CHICKS ARE SNEEZING. Should I worry? Should I do anything? They are still running and jumping and being crazy. Is sneezing normal? I don't remember anybody sneezing during the week they were in the house. They are eating and drinking constantly Thanks for any advice?
