In a hatchery setting,yes I agree,but in a private collection,there is no need of it.If they are pecking each other they do not have enough space and should be placed in proper surrounding and no tampered to suit your needs.They need to feel as natural as possible for good productivity and health.Blinders definitely have there place, some have a plastic pin others use a metal ring. some are plastic others are rubber. I found that the rubber with the metal ring (hog ring) would work the best. They have a tendency to fly up into the top netting and get caught , the rubber ones eliminated that problem.
they also have a bit that prevents them from being able to close there beaks all the way, I would not recommend these if you are feeding a pellet.
It will not affect if you release into the wild, just be sure to remove it prior.
Birds four to five weeks old is the best time they become accustomed to them very quickly. pheasants go Thur a time of abnormal aggression the six week and the 12 week, once the cannibalism starts you are only fooling your self if you think you are going to stop it. reasons for blinders I feel is if birds are over crowded, to hot in the brooder, not enough vegetation in the fly pens (green vegetation does wonders) problem is it is often gone very quickly in your pen, good game bird feed really helps from start until it cools of in the fall. usally if you can get them out of the brooder with out the problem you will be OK. Debarking is a good way to solve the problem . but to do this right you need a debeeker that has heat, simply nipping the point of the beak of will not solve the problem, it will grow back quickly and often sharper. using a debeker takes some talent and precautions you only cut the top beak, dint cut or burn the tongue, a good 1/8 inch will work but the heat stops the bleeding. the downfall to debeaking is the beak grows back longer and ill shaped which means you have to keep following up with it about every six weeks.
The whole secret to this is don't let them get into the habit of peeking each other.
I hatched 60,000 chukars and pheasants and grew out 18,000 to 22,000 of them for sixteen years. I have tried it all they have there pro's and con's. it wasn't until my later years of trial and error that I was able to get over the cannibalism and pecking it all starts in the brooder, if you would like some ideas on brooding let me know.
