There are 3 species of Buckthorn native to Europe including the UKI was talking about berrie fruits from bushes and trees we don’t eatsuch as elderberry and hawthorn.
I never gave pieces of citrus peel to eat. Citrus fruits are no problem. But when I solit an old orange or mandarin they leave the (half) peel for me to discard it.
Btw, the text in the spoiler was translated from a Dutch explainer site for teenagers.
My chickens eat apple seeds quite often. I never had problems with apples seeds from pears, grapes etc. at all.
P.s. my chickens don’t eat from the ivy. And I have no idea what Buckthorn is. Its probably not common in Europe. The very poisonous ivy doesn’t grow here either.
Alder Buckthorn (Frangula alnus) which prefers damper more peaty soils & is not thorny
Purging Buckthorn (Rhamnus cathertica) prefers chaky soils & is thorny
Both the above are in the same family, have black berries & have been used medicinally but can have rather unfortunate results!
Sea Buckthorn is the thorny coastal one that likes full sun, has narrow, silvery leaves & orange berries which are full of vitamins & apparently can be used to make a rather good jelly
