I don't know. Hopefully someone with more knowledge then I have will see your question. Until then though I wouldn't do it. I do know that it's bad for dog and I think cats too. Do you have any childrens Tylenol? That's usually a safer choice. Good luck!
I have heard that Ibuprofen is bad for chickens and that asprin is the only thing you can give. I've also heard that chickens have a very high pain tolerance and seldom need pain meds but I'm hoping someone with more experience and/or knowledge will chime in.
