In other words -- about 7-10 days PAST the full moon, we follow that for anything stressfull -- castrations too. We are at about 70 % moon now, 3-4 days to full -- and another week after "HE" will be less than 50% -- apparrently perfect at that point!
Can't say why it works, but our calves bellow less, and go to feed better -- if the moon is slightly dark, not too well lighted. Amazing stuff!
