I have six Buffs that are 11 months old (they have a rooster.I only have 3...sometimes 4 that are laying.I got them a little over a month ago...I was told they were all laying.I thought maybe the move stressed them out .But like I say it has been over a month why arent all of them laying and what can I do to encourage them to lay.The 3 that are seem to all lay in the same box.I feed a good laying mash.and some scratch they also get grass and table scraps and I feed them broken up egg shell crushed into little bits.Thanks in advance for your help...
