Q: At what age do hens start laying eggs?
A: On average, pullets, or juvenile hens, start laying eggs at about 6 months of age, depending on the breed. Larger, heavier birds like Wyandottes, Plymouth Rocks and Orpingtons will lay on the later side whereas lighter, smaller breeds like Leghorns, Stars, and Australorps will start laying sooner. However, if your birds come into maturity at the coldest, darkest part of the year, they will sometimes not begin laying until spring: six months is just the average! We guarantee you that every day past five months that they haven't begun to lay will seem like an eternity!
There are a number of reasons your chickens might not be laying, though, so if you suspect there's something more to it than this, have a look at this list of other possible reasons your chickens aren't laying.
