Well next week my not so little ducklings will be 6 weeks and are going to have to vacate the spare room. My in laws are coming for a visit so the babies need to go into the garage. They are still on heat and will have a lamp in the garage but it's suppose to hit freezing most nights and be in the 40-50's during the day. I'm pretty sure they will be just fine but I need reassurance. I'm particularly worried about one of my runners. She is small and has no meat on her and isn't nearly as "fluffy" as everyone else. She is healthy I just worry about the cold and her. Right now my house doesn't get below 62 and under the heat lamp it's been about 68. Yesterday and today I have only had the lamp on at night. My garage will have an air temp of 40-50 degrees. They are mostly feathered now except for the backs. Their lower backs in particular have no type of adult feathering.
