Hello, I have rirs’s one is around 6 weeks and the rest are 5ish weeks. The one that is 6 weeks is fully feathered and the rest are almost fully feathered but still have some down on them. Once they are all fully feathered will they be okay to be outside? I live in New Jersey and the weather is around 60-70 degrees in the daytime and around 40-50/60 degrees at night. My neighbors have been telling me that I will probably need to keep them inside all winter but it’s not really ideal. They don’t really sleep under the heat lamp anymore, and the temp in the garage is about the same as outside maybe 5° warmer. Do you guys think It will be okay to have them outside once they are 6 weeks and in the winter? Thanks.
