I had a silkie pretend to go broody on me last week (I think she was practicing), then on Tuesday, I realized that she actually might be broody for real. I moved her to a brooder box & waited 24 hours to be certain that she is broody. Yesterday afternoon (around 5pm) I switched out her golf ball eggs for five real eggs. So would yesterday be day one or is today (Thursday) day one? Or does it matter that much. Lordy, I am almost as excited as when I found out I was going to hatch my own egg! Thank you in advance for the answers. I've found that no matter how dumb my questions, I've always gotten answers here!
