Opening nesting boxes

[aart]

One of the other posters a couple of days ago said their red sex link layed at 13 weeks. I thought it was wild too but they were adamant about it...

I suppose it's possible...but...rare even for a sexlink.
Average onset of lay is 18-28 weeks for most breeds.
Diet and time of year(day length) can have an effect.

The earliest I've read was 14 weeks.
My Red sex-links didn't start till 16.5 weeks, them slackers. GC
