My RIRxEE layed her first egg 10 days ago at 21 weeks old. The problem is, she hasn't layed an egg since! I mean usually they lay their second egg two or three days later but now 10 days later, still no egg! Why is she not laying??? All the other hens she is with are laying, despite the rather high temperatures. Her half sister started laying only 3 days ago and I got her second egg today.
