I have a hen who I have been keeping close to me because she is not able to get around on her own. I dont know what is causing her paralysis but I did notice she passes these hard, red pod-like, seed like things ever so often. I strictly control her eating so I know she it not taking in anything like that now. It could be something she ate over a month ago and is still going through her system, but Im just hoping someone will have an idea as to what it might be and if it could be the reason she she having difficulty with her legs and wings. Here is a pic of three of them next to a penny for size comparison. They have a heart-shape but the point is like a sticker, very pointy and sharp. Please, if you have any idea what this might be or where I can go for information on these pods, please let me know. Thanks so much for your help and concern in this matter.
