I mainly hatch The Normal Chickens---LOL, Yellow Buff, Barred Rock, Gold Laced and Blue laced Red Wyandottes, White Leghorns, silkies, Old English game, Rhode Island red, Speckled sussex, Black copper and Blue copper marans, Welsummers, etc. I started this as a hobby back in june when I built a Incubator and hatcher out of some scrap things I had laying around mainly. I have hatched around 1200 so far but I bought alot of hatching eggs from a Auction---alot of them were not fertile or to old etc---so I only had a few of each dozen to make it to the hatcher. Now I am hatching my own eggs---most all of them hatch. I was putting almost a 100 per week in the incubator but I am in the process of shutting down the incubator/hatcher for about a month or two. I took 80 out the hatcher last week and 82 the week before etc, etc, etc, etc.
