I have recently implemented several no crow rooster collars on several extremely loud HENS:hide


Im asking the question on proper placement of the collar, Ive heard that lower on the neck is better (proper) than higher.


The reason im asking this question is because after I put on the collars I noticed that the hens developed like a mass of food on the side of their upper throat, it didn't seem to bother them at all, they were eating, laying and foraging normally. After I removed the collar the mass was gone (maybe swallowed) within an hour.


Does anyone have experience with this?


I can try to take a picture if it would be helpful, thanks everyone
