Great read on Cots, alot of questions answered here. Hope it helps.
I am totally at this stage right now with my choice too... I just got the 50 Bobwhite eggs i ordered to incubate and see which i like better, man this is exciting! Good luck with your decision, its a tough one but try things out and just watch them so they dont kill each other.
