I did the same thing at my local Tractor Supply today. Went to go pick up their feed, and lo and behold, 'Chick Dayz' have begun. Checked out their new set-up... professional stacked brooders where you can see the chicks up close and personal, with heat plates above them, rather than the horse troughs with the red heat lamps inside a dog pen inside the store. I LIKE the new set-up! However, they only had Golden Comets (aka Red Star Links, ISA Browns, Cinnamon Queen, et al) and White Leghorn pullets. I'm going, nope... already got enough ISA Browns in my flock (pullets almost to laying age... another week or two and they will be), and my personal experience with the leghorn breeds has given me enough to know I DON'T want leghorns in my flock again. So, I walked away from the chicks today. So proud of myself. However... I'm testing the fertility of my Barred Rock roo with my Black Sex Links and Barred Rock hens, so have eggs in the incubator, with Silkie eggs on the way, plus now, Toulouse geese hatching eggs. I'm in BIG trouble, as I have 21 pullets almost ready to lay, 2 that are 4 weeks behind them in age, 5 egg-layer hens, 4 meat hens (Freedom Rangers) that have become dual purpose... they lay HUGE brown eggs, regularly, every day... such sweet, docile birds that I hate to have to cull them, but if the time comes, I will. So, yea, chicken math IS real!
