We have 3 chickens who normally seem to be very happy, they lay every day, however 1 of the girls has been in the coop for the last 3 days and is very reluctant to leave it. Also we have noticed a drop in the amount of eggs they lay over the last couple of days.

To look at her she looks well but i find it strange as to why shes staying in the coop?

It sounds like she could be going broody.

See here  to see if any of this rings a bell
