Sounds like fun with the egg!
!!Just be patient with the laying, they´ll get back to it. I have some ISA browns, Rock-mixes and Brahmas, so I have a fairly constant supply of eggs, but even the ISA browns have their breaks. Right now I have 2 out of 3 moulting Rock-crosses laying, and 3 out of 5 non-moulting ISAs laying! The brahmas are brooding. Some days I pick up 7 eggs, some days just 2!
About 2 months ago I went to a place that sells birds. It´s all very pretty there and they´re well looked-after, but they charge a packet and I refuse to pay those prices, so I asked him if he had any brahma eggs for sale that the chickens had laid. He said that as it was raining the chickens wouldn´t lay. OK, interesting I thought. So I paid more attention to mine, and I think it´s a theory that´s a bit hit-and-miss. Maybe there´s something to it.
Also, the shortest day has a lot to do with it, and it´s just around the corner! When the days start getting longer, you´ll see them start to lay again.
