Pullets that are laying are now not laying eggs?

[debrob904]

I have 2 RIR/White Rock mixed pullets at least or over 20 weeks. One gave me 4 eggs already in 4 days today they was no egg.
Any ideas or comments?

there body's just getting used to laying it might not be real regular for awhile. not to worry
she will start to become regular soon.

I am Supposd to buy hens that look healthy . Only 2 are laying . They are being kept at a farm that was just raided by dogs. They killed many animals. They are also in a coop that is too small . Could that be the reason and will they possibly lay again?
