Here it is 6:49 p.m. and I have an EE on the nest. They lay all during the day here. That rumor that chickens lay only in the morning is like the one that roosters crow only at sunrise. Nope.
Mine lay at 8pm! and one lays at night! around 10! She sleeps in the nest box and when I go at midnight she is in the nest box and an egg! they are OK =]
Why do you imagine there is something wrong... is it because someone here said this or that? A public forum is like asking a question in a crowded room - you'll get all sorts of answers. They can sometimes be, well... divergent, shall we say?
Most chickens lay in the morning hours, but there are always some who go against the grain. You can never predict what a chicken is gonna do, all the time. They are living things.
Besides, we sometimes cause such behavior ourselves. We feed at irregular times, for example. Or we hover around, run the lawnmower or dog back and forth constantly. They are creatures of habit and disturbances like this tend to do drive them to laying eggs when we're not near.
There are ways to regulate them that have been recommended over the years, but they are more involved than just pouring the feed to 'em, 24/7.
May I recommend you relax and be grateful for nice chickens that lay well. Then, take 'em a few Cheerios, tell them thanks for all their hard work and just kinda go with it.
i am so glad to hear that i'm not the only one with crazy chickens. mine were morning layers then one day they became afternoon layers. the only other crazy thing they do is they lay in a hole in the ground. i don't know why they just do. but what ya gonna do.
