Hi I have 4 RIR and a white rooster unsure what kind he is. I got them at an auction fully grown. Have now found myself wondering if they have stop laying is the reason they were sold. 4weeks in getting one egg a day. Do you think it will pick up? Also just got 8 chicks. (What a handful they are) 

and Welcome To BYC! Good luck with your new flock! X2, stress like moving to a new home will make hens stop laying for weeks or even months, eventually they will usually pick back up if nothing else is wrong. Do you know if all of the hens have laid eggs since you got them, or has it been only one or two? Be sure to give them a really good going over looking for mites or lice etc and check their body condition. You might also consider going ahead and worming them since they aren't laying much anyhow and since worms can really drag a hen down, and you don't know their history. Do you have them on a commercial Layer food etc?
