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?

Can't find any mites. I dust regularly for them. Definitely a bit of molting going on.

@ricklee I have 2 Isa Brown hens.

1 is laying her usual 2-3 brown eggs a week. She is almost 5

1 is like your, suddenly reduced in egg laying and her egg is now white colour, but she has been having soft shell egg on/off and have been getting calcium+D on and off. Her egg not only change from brown colour to white, the shell is easily crack also. She is sort of molting, that is I see a small handful blood pins on her feather, and her feather are tatted bad looking, she is skinny like just skin cover her bone.

She eats like a pig, dig up my garden especially in this muddy wet condition, her face and comb colour is light pink and looking a bit bruise. I am suspecting she is in some sort of ill health, I just don't know what. I monitor her closely every day - checking bum bum, poop, and general signs of ill health. She is just a bit over 2 years of age. From my personal experience with Isa Brown, they are getting into reproductive issue around this age.

I hope all is well with your hens
