If the extent of your research is BYC, and not a scientific research project, then your opinion is no more than that, an opinion. Which you are entitled to, of course, just as much as I am to mine. I just want the readers to understand that these are just opinions, not actual fact, so they can draw their own conclusions and go with their own preferences.
I grew up with farm animals and the chickens always ate peppers and tomatoes, seeds and all. Never had a problem with them. My current chickens also eat peppers and tomatoes, with the seeds, and have never had a problem. I am very interested in a real scientific study on the matter though, so if your online research leads you to one, definitely do post it here.
