2 black marans completely stopped laying - ?normal

[khoitsema]

I have two young black marans (less than a year old) who were laying 1 egg/day each. As it got colder, they slowed down laying, and now they've completely stopped. I've heard chickens slow down in the winter time, so I didn't think much of it until my uncle said his chickens are still laying everyday. I live in a very mild climate, its usually 5-10 degrees celcius (40-50 degree F) throughout the night, and about 80-90% humidity (we have a thermometer inside the coop). We recently bought a little heater, so that may make a difference but it's too early to tell. We have a tractor-style coop, so it's directly on grass, and its moved daily. Also the roost part of the coop does not have a floor (so the poop falls directly onto the grass) but I worry that there's maybe too much airflow for the girls at night. Anyone have any thoughts? I really don't mind not getting eggs in the winter, but I just worry they are stressed out.

Temperature has almost nothing to do with it. Declining day length is what causes laying to cease.

They do not need heat at 40°F.
It won't make them lay,
day length is likely the issue and Marans are not stellar layers anyway,
and could make matters worse.
Is the humidity outside the coop 80-90%?

This is your tractor?...I see no ventilation near the top?
So all the moisture from ground and breathing can't escape.

Where in this world are you located?
Climate, and time of year, is almost always a factor.
