One hen not laying - everyone else is

[bigskycornsilk]

I have 4 hens of laying age (all are under a year old). Up until earlier this week, all were laying consistently. I now have 1 hen that has not laid in several days. (I know it's just the one based on egg colors -- she is my only brown egg layer.) Everyone else is laying just fine.

She doesn't seem to be lethargic AT ALL -- in fact, she is her usual self. Eating and drinking fine, no penguin walk or anything. I even checked her for a stuck egg, but there was nothing. The only thing off is that she's missing some feathers by her vent, and had some poop stuck to her. The only other change has been temperature over the last week. We had our first frost and nights have been consistently dipping below freezing. Could this have stopped her from laying? If so - will she begin laying again soon?

And if temperature isn't it, what else could it be?

Ita not temperature, it's low light, it's normal for most birds

Is she just more sensitive than my other birds? 2 of my other girls are still laying daily - though they are a different breed

If it is fall where you live, she probably stopped laying because she doesn't have enough sunlight, she will start again in the spring. You can supplement light too, so she will lay throughout the darker months.

Maybe. All of them are different.
Often pullets keep laying all their first winter, others don't.
She may have a partial molt too.

All birds are individuals so yes, she could be.

Daylight does affect laying, but something to note is you said “several days” it is actually very normal and healthy for chickens to take a few days off from laying at any age any time of the year.
