How do you know that they are infertile? If you are sure they are infertile you can take them all at once.. Odds are that she will start laying again and hopefully this batch is fertile!! Good luck!
How many eggs did she lay? Arent they sooo cute when they broody and rounding up the eggs underneath them!
Dee layed 4 (1 every other day) but i did remove the first one because i dint know that i wasnt supposed to. So she actually replaced the one i moved, so 5 eggs in total.
If it happens again for you or if anyone else reads this... yeah just do not take away the eggs coz it can mess up them up trying to replace all the eggs. She will sit on them for ages and only get up to eat and poop, and be all bitey and hissy (well more than usual! lol)
She will eventually leave the eggs and you will know when they are done with trying to hatch them...trust me you will know!
