Hello, we FINALLY have a bator YAY We are looking to set eggs to hatch around Feb 1. We have ordered 25 from McMurrary that'll be here that week and we'd like to set eggs to be hatched around the same time... Any advice for a newbe??? When should I start holding eggs back for hatching? How many should I hold? When should I set them in bator? What is lockdown?? Any special suggestions?? Thanks in advance guys (and gals) !!
