First, how old are they? Many people think that chickens start laying at 20 weeks old, but in reality, it can vary from 5-7 months. Anything within that time frame, and even outside of it, is still a normal age for egg laying.
Is there any place that they could be hiding eggs? Do they free range? Sometimes, it will look like birds aren't laying, but one day, you'll find a stash of eggs in a random place.
Because daylight hours (at least in the United States) are decreasing, it is possible that yours won't start laying until spring. Ideally, chickens need at least 14 hours of daylight for maxiumum production. But, if yours are pullets that haven't laid before, they'll likely lay through the winter despite the short hours.
They will lay when their ready there nothing you can really do right now I have a six month old hen that isn't laying so its un not uncommon
What type of feed do you feed them? This can also effect egg production
I'm hoping that someone will be able to help me. A month ago i got 2 Black Star Chickens. about a yr and a half old. they havent laid a single egg yet. The man i got them from said they where his best layers and laid 2-3 eggs a day each. but yet i have not one egg. so......How long do they need after moving before they lay eggs?
2 to 3 eggs a day EACH? Not possible. Either you misunderstood or he misrepresented. If they really are a year and half old, it's possible they're going through molt and also not laying because it's heading into short daylight hours. Combine that with the stress of a move and they'll probably start laying in the spring. Of course, if this person you got them from lied about their egg production, it's also likely he lied about their age and they're past laying regularly.
