So I have around 50+ chickens and the oldest are about 1 3/4 years old. None of them have molted or showing signs of molting anytime soon. Is that normal? All of my hens/roos NEVER have molted, and I hear they they start molting around a year. Should I be concerned?
Sounds pretty normal to me. There are different things that can cause a molt any time of the year and at any age. A really stressful event like running out of water for a couple of days or a predator attack might trigger a mini-molt or even a full molt. I've had broody hens molt in late summer when raising their chicks months before the rest molt. If they have been laying for a long time period, like maybe over a year, they can get kind of worn out and need a rest so they might do a mini-molt.
The main thing that triggers an all-out molt is the days getting shorter. They are programmed to lay eggs and raise chicks in the spring and summer when food is plentiful. Then in the fall they replace worn out feathers and quit laying so they can use what they eat to grow new feathers instead of making eggs. Then when spring comes around they start laying again.
We've messed with this cycle some by domesticating them. Sometimes we provide artificial light so they don't know the days are getting shorter, maybe on purpose or maybe by accident with security or street lights. We provide then a rich diet year around so they don't see a drop-off in nutrition during winter. We've bred them to lay a lot of eggs instead of just enough to raise two or three broods a year. We've bred them to not go broody that much.
So now it is not that unusual for pullets to skip the molt their first winter and continue to lay until the next fall, though production may drop some toward the end of that laying period. With lights and a rich diet some even go broody in the middle of winter. But one thing that is pretty constant as long as you don't mess with the lights is that they will molt at some time in the fall when the days are getting shorter after that first winter. So get ready.
Some chickens are fast molters, some are slow molters. That's controlled by genetics. It's not how fast the feathers grow back it's how fast they fall out. With fast molters it seems they can go almost bare overnight. They look horrible. With slow molters you may not even notice they are molting by looking at them, the only way to really tell they are molting is that you see a lot of extra feathers flying around. But eventually they look all sleek and shiny. Fast molters are generally better producers.
This time of year in Kansas I'm a little surprised you haven't seen some extra feathers flying around, especially in the coop. Maybe there is something in your set-up or you are treating them so well it's delayed a bit. We are all unique. This kind of stuff does not happen at exactly the same time from one chicken to the next, let alone from one flock to another.
Don't be upset or worried if you see them eating some of the feathers flying around. Those are a free source of protein that mine take advantage of. There is nothing wrong with it.
Good luck!
