I hear that Honeysuckle is not a good idea. Problem is- it's rampant all over our property. I do the best I can not to let them get at it, but I know a few of them seem to seek it out. When I first got chickens a couple years ago, I was unaware it was bad for them. The yard that they are kept in is surrounded by it. It was even growing on the fence and they had been eating it for quite a while before I found out it was toxic. There have been no fatalities but I will say that it sure does give them runny poo.
