Out of 19 eggs in bator, 8 have hatched, four upside down. I lay them on their sides to incubate and lockdown blunt end up. Never had one upside down before, but ave had to tip up four of eight chicks now so they can get out. Last one only had a leg out frantically trying to right itself. When I lay it down it just spun so I had to remove the end of the shell. Also got one zipping clockwise. What's going on???!
