Chooks stopped laying

[ricklee]

Hi all, I need help. I have four Isa brown chooks. 2 years old. They were laying 4 eggs every day, then two. One egg suddenly white colour and has been for two months. Now the other egg is white. Last few days down to one white egg. It's now two months. I've wormed them. No mites dusted anyway. Can't see any hidden eggs. Combs are nice and red. One chook a bit of a molt going on. No sign of predators. I'm feeding the Vella layer pellets. Any help please

They have reached the point where they are taking a break in their laying cycle. Shortened daylight period and their age has triggered this.

Hi and thanks. I'm in Australia so late spring here. I would have thought a gradual decline at about three years. This has been quite a drop off.

Hopefully as your daylight period increases, they will resume laying eggs.

Close up of feet and face please! You're right that this behavior in Australia doesn't make sense right now. Have they been acting weirdly at all aside from the eggs?
I'd assume they have all caught something. The color suddenly stopping is a mystery.
Otherwise, they all could? be molting and slowing down for some weeks due to that, but that still doesn't explain the brown pigment stopping.
Do you think mites could be a factor?
