Are you saying the neighbour took it or it just got away... and then the neighbour kept it? Mine are 2 Isa types? Highland highbred high something? One was older when we got her, I thought the other which was one I first got when I started this thread was young when we got her? Ever since the move they have stopped. They had started to lay again the days before we moved. They don't like the city? 😞 2 fart eggs is all we've got since 5th Dec. Don't have the heart to chop their heads off and simply can't get anymore in the city. Small coop now anyway....

I think if they wander into the neighbours yard they apply the "finders keepers losers weepers" rule.   I've caught them before but now they've mooved the coop I can't really go look without accusing them and unless I know for sure I don't want to start neighbour wars.

Go buy some layer mash and up their food intake.   They should still lay in the city.     If they're Isa types they'll only lay for the first year.
