Not knowing where you got your birds. Just wondering if you are absolutely sure they are all hens. Many times folks buy chicks and find out a rooster is in the mix. Maybe post a few pictures of your flock to be certain. Three months is a good time to post pictures to confirm you have all pullet.
this right here. I love the sound of the crow but they crow all the time.... "OMG A CAT!!" Crow!!!! "OMG A BIRD!" Crow!!! "OMG A CAR!" Crow!!!! "OMG A LEAF!!!" Crow!!!!!
I do agree about them crowing all day, dont know about your neighbors
