I have 20 hens and four roosters and by later winter I am going to start hatching my some chicks. I have some breeding ideas and I want to hatch some for meat, some to add to my flock and some to sell. This will NOT be a huge operation and is really just a hobby. Not into it for money at all. Been looking at several and I think I want an auto egg turner. So....what do I want and or need? I have the wife talked into it being my b-day/christmas present, but not wanting to spend a fortune either....please tell me everything I need to know.
