Stopped laying

[oldhenlikesdogs]

They are right around a year to year and a half. Half have molted but I see no sign of molting on the other half

They generally take at least 6 weeks to 3 months to molt so I don't think you are seeing full molts yet? I'm seeing some feathers lying around and a few are growing in the bald patches.

I'm guessing that part of your birds are molting and are not done yet, they won't lay until the molt is complete.
Your avatar shows a nice mobile coop....do you free range?
They may be laying out in range area after the attack.

I was getting 10-12 eggs a day. Now 4-5. The are out in the yard in the afternoons for a bit. Don’t see many feathers lying around yet so didn’t think about molting. Thanks. We built the coup on a trailer we weren’t using out of pallet wood and insulated well because we are in Minnesota. Rain barrel and all! Lol. Giving the ice in the water now too.

They may either have a hidden nest(s)...or they can stop laying before the feathers start to fall out.

Would love to see more on your coop, and how you handle winter.

A box fan in the heat and a heat lamp in the cold keep my girls laying year round! During heavy moults I mix in chick starter with the layer feed.

Birds older than one year need white light ~14hrs per day to lay in winter....
...they don't need heat unless it gets and stays below zero F 24/7 for days on end.
