I have 16 two week old ring necks, and 42 due to hatch in a few days. Soon after that I'll have another batch of 40+ eggs going into the incubator, so I will soon have a hundred or more pheasants that will take up residence in my pheasant growout pens. Looking at limiting the amount of issues due to pecking. I've seen clip on peeper, perfect peepers, and economy peepers. The cost isn't an issue, just need to know what works well. Thanks in advance. Each pen is about 1,200 SF.
