My hen does not lay eggs?

[lizhejerry84]

I have three chickens, one rooster and two hens (black and grey),
breed: Ameraucana
The grey one started lay one egg per day regularly about a month ago.
However, the black one may lay one or two in the past and no more later.
they are about same age, almost one year old.
I confirmed they don't lay egg somewhere else. (they are in a small fenced area)
they are eating same diet, I guess.
Calcium? I don't provide extra oyster shell, but just some crushed egg shells.
Any ideas? Thanks

What all and how exactly are you feeding?

I just leave the layer feed there, some corn and grain, vegetables and fruit, free range, so not really control exactly what they will eat.

Stop feeding anything but the layer feed for a couple weeks, see if that improves things.
Does the non laying bird look like she laying?:

I will try only with layer feed first. thank you for the clarification.
For butt checking, with rooster, it is not easy in the daytime.

I do all exams off the roost after dark, wearing a headlight.

I will try it, thanks. I know chickens are kind of blink after dark.
