My ducklings are almost 5 weeks old! There coop is almost done being built. It should be done this weekend. When can they go outside? I worry because I live in nh and it still gets chilly at night! During the day it is 50s but at night it can still be in the 30s. Any suggestions would be great! Last week it was beautiful 70-80s so they did get a lot of outside time! They are much happier outside!
