My new young chicken has stopped laying!

[Charliepw]

I am new to this chicken malarky but quite enjoying it.
We bought three chicks/chucks about three weeks ago who were apparently at point of lay then.
The brown one's comb is the biggest and she laid around 5 eggs in total right at the beginning every other day, then she stopped.
She used to crouch when I stroked her but now she doesn't seem to crouch at all.
The other two are starting to get bigger combs but they still look like little mo-hawks

do chickens go in and out of lay?
Is this normal?

Yes they do, largely depending upon the time of year and the breed.

What breed are they?

Does she seem well?

Hello
thank you for your answer.
I didn't realise they could go in and out of laying, i knew they stopped in the winter, but not in the summer!

they are all hybrids, and i'm not sure what breed they are.
I could recognize them, if there was an online chicken library.
they are normal size big chickens.

She seems fine, she walks around as normal, so i think she's ok.
I'm not sure who the boss is yet, i thought it was her, but now i suspect it's the larger white one (who has the smallest comb)

thanks for your input.

If she doesn't seem unwell, then don't worry about it. Hybrids are usually pretty reliable layers and don't go broody as often as some pure breeds.
