I have used them twice now and am very happy. Both times all chicks were alive and healthy. This batch is now 2 months old and I have only lost one chick (they added in an extra, so I'm still at 25) I have used three other hatcheries with not as good results.
They also have a great sexing rate. No roosters!! Both times.. That is awesome. I highly recommend them and will use them again in the future.
