It's a late spring in Seattle, highs in the 50's and lows in the 40's. Should get up to the 60's next week but may dip down a bit again. My 3 chicks are 8 weeks old and ready to go outside...and we're ready to have our bathroom back! They're all feathered out and flying around in their brooder, all perfectly healthy. Will they be all right outside in these temperatures?
