Hi All Is parsley poisonous to coturnix and/or button quail? - According to this page it is: http://www.wikihow.com/Feed-Quail - And according to this list (eventhough for parrots) it also appears poisionous: http://www.plannedparrothood.com/plants.html So maybe there is something to it when it's poisonous to another bird too? This is ofcourse not a matter of your quail will drop dead or even just looks sick if it eats parsley. It will even in those cases try to hide it as they tend to do with sickness. This is ofcourse a matter where we need to see inside them... are their organs negative effected by parsley?
