Hens have stopped laying!

[Thenewman3]

I have a barred rock, 3 EE, a black sexlink and black australorp all of which are a little over a year old. I was getting up to 6 eggs a day. We just introduced 4 new Rhode islands two weeks ago and all of a sudden egg production has stopped! I collected two eggs today, one of which I believe is from one of the new hens because of the size. What is going on??

Something as simple as adding birds to a flock and the resulting shake up in the pecking order can cause birds to take a break in their egg laying.
