So 2 days ago, 2 of my hens were acting really strange. They were off balance and really sleepy. After much searching and racking my brain, I realize they got into my daughters plant for her butterfly garden and it was foxglove. So for 2 days they have been in my house sleeping, but not eating or drinking much. Is there something else I should be doing for them? Is there a way to get the poison out of their system. Thanks!
