I am getting chickens! I am very excited!However I am not sure how many I should get.We have a pretty small garden,I want two ideally,but I am getting a chicken house that would house up to six.will they mind having a roomy house?would three be better? also is three better generally ,or if you have two,and one dies,is it easier to introduce a new than than it would be to bring a new hen in with two?All advice appreciated!
