Hi, all, One of our 2 1/2 y-o hens seems to have displaced or injured one hip, based on how she moves that leg. She can get around pretty well most days, but when it rains,she barely uses that leg, almost dragging it. So whatever the original cause,she acts as if she has arthritis. I want to give her aspirin to see if it helps on those bad days. I've found the ratio for the mix, but if I give it to her with a dropper, any idea how much I should give? We have 35 hens, so I don't want to put it in the general drinking water (I see some comments expressing concern about long-term effect). Thanks very much for any thoughts!
