Hey, I have a new flock 4 girls (2 leghorns and 2 black sexlinx) I'm new to the chicken thing, and I got 3 little eggs this last week! I was so excited, but now nothing... I did take them out cuz I was so excited. Do i need to have fake eggs for them to start up again? (A friend said to just use a golf ball..) they are 24ish weeks old.
