I bought some pinless peepers and pliers to put on a few of my bully chickens. I tried to use the darn things and I cant figure out how to get them on the chickens without pinching thier nostrils shut. does any one have any recomendations? or experience with them or should I sell the flippin things and deal with bully chickens? there were no instructions included with them either! and the pliers were 20 bucks and dont seem to work to open the things up wide enuff to get them on them!
