Here we go!!! This is a year long HAL for hatching by the moon. Set so eggs will hatch during the waxing moon during the fruitful signs. SET DAYS FOR CHICKEN EGGS FOR THE FIRST 3 MONTHS OF THE YEAR ARE January 19-21 January 27-29 February 15-17 February 23-26 March 22-24 March 31 - April 1 For other birds, please adjust set dates accordingly. I stumbled on this old thread about hatching by the moon phases and sign. https://www.backyardchickens.com/t/536525/hatching-eggs-by-the-moon-thread So for most of the year, I'm setting eggs so they'll hatch under a waxing moon in one of the fruitful signs of Cancer, Pisces or Scorpio. ... Every location will have somewhat different set times. You can find your set times by going to http://www.lunarium.co.uk/calendar/universal.jsp, enter your location and the resulting calendar will tell you when the moon is in Cancer, Pisces or Scorpio between the New Moon and the Full Moon.
