Today (luck of the Irish, please be with me!) is hatch day by my calender. My eggs/chicks may not know this, but it is. When and if they begin to hatch, what should I look for from my broody? What I mean is, will she give me any indication that they are ready to hatch? Will she get off the nest? Will she stay there? Will she get up & dance a cha cha? What should I watch for? What should I expect? Thank you in advance.
