6 months old and no eggs

[dokam]

I have 4 young hens - they were 6 months old end of September. One has been laying since she was 5 months old - nothing from the other two. Is this normal?

We have an Australorps that will be 25 weeks old this weekend...still no eggs. Comb and wattles have grown and are bright red. Always chatting up a storm. She did attempt an egg song a few weeks ago but nothing since. Always exploring the nest boxes but never sitting. She is holding out on us. We are in the city so they aren't free ranged but are in enclosed run so she isn't laying anywhere else. Other hens are 21 weeks old...starting to think might get an egg from one of them first..
