For the last two days my chicken can only stand up briefly and walk maybe two steps and then sits back down. She does not appear to have an impacted crop. I cannot feel any egg block though am not sure if she is laying. She was in excellent health and is under a year old and was laying regularly. She is dragging herself around to the rockier areas of the yard and eating many small stones. She is still eating grasshoppers and sunflower seeds offered to her and seems alert. She is passing poo albeit it with undigested seeds in it. She has always had access to the yard with many small stones for her crop. All my other chickens are in great health. This chicken was the 'boss' chicken and was always the one to eat the tasty morsels. I suspect this may be related to her eating something, but what do I do to help her? I have tried water and oil but to no avail.
