Some plants are poisonous to chickens although fortunately they are quite savvy about what not to eat and it is very rare for a chicken to eat a poisonous plant.

Here is a list of some plants that are poisonous to chickens, it is by no means exhaustive and I haven't been able to verify whether they really are poisonous of course. The list is based on what people have told me over the years of running the site and I have picked out of old poultry books.

If you know of any other plants that are poisonous to chickens then please let me know so that we can share them here. Thanks.
