Okay, he's a bantam, about 5 years old. He has always been very healthy and feisty. He eats layena crumble, grapes, cat food, corn, bread, it varies, there is always crumble. He is cooped with other chickens as well as Guinea Fowl, and is out in a large pen during the day. He started having this...
I tryed soaking his back end in warm water and gave him olive oil to eat in his food as well as putting a milliliter or so in a needleless syringe and gave it to him as an enema, but he is still not going, it's just brown water, and now, olive oil. He has been straining to go for hours.
