Very true, thanks for this. Merely disagreeing is not intolerance. We need to be able to relate our experiences with this stuff and let people decide for themselves what is relevant to their own situation. I have about 50 layers/breeders, 6 roosters and a continuous flow of young ones just passing through on their way to the feed store or to freezer camp; adults and juveniles free range. I use zip ties to keep the identical birds straight and it works very well for me. I figure that I have to check birds regularly for mites and for injuries and for bumblefoot, etc. Checking also for zip tie problems is just done at the same time.I don't see intolerance at all. You could say the same for the poster that was against them, his attitude/delivery was not good.. People were just saying on their experience that they aren't ALWAYS a bad option. No one gave him the same delivery he gave everyone else. The situation he gave just happened to be a massive operation, not really relevant to the original poster. We can find pros and cons all over about one topic.
Intolerance would be people telling him he can't voice his opinion at all.
