X 2! And, did you look up the type of cactus? Some cactus plants are not fit for man nor beast. The poop is awful yellow to me. It may be that this feed is high in corn but it could also be something else. Give him the bread with the oil, if you can get him to eat it. Look up the cactus and see what type it is. This may just be stomach upset from something in the plant or it may be something more serious. I don't know this feed so I can't comment on it. The other tom that died, did he also eat the cactus? Did he come from the same place you got this one from?If he is drinking water willingly, that is good....i would continue trying to give him the vits and healthy bread with oil, probiotics/yogurt to help with stomach flora.....if you have other poultry feed or cob/scratch or food scraps see if that interests him......if with other birds, does he follow them if you scatter feed? If you have other livestock and keep on hand *Red Cell or *Goat Nutra drench, i have diluted it in my poultry water for extra nutrients/iron on a limited basis. Drinking without eating is ok for a short while but will need calories to keep warm and survive. If you have other turkeys to check difference, does he feel warmer as if feverish????
Do you notice any difference in his neck that could be a swelling or if held and you gently touch his neck do you feel anything or is there a point where he reacts as if sore?
Is he where you can monitor his poop, color and amount without stressing him? Think that the Yellow coloration could be toxin related? So as long as he continues to drink maybe could flush out of system????
Just some thoughts.....
I just read your post again to make sure I didn't miss anything. You say he walks by the food, I am assuming you have female turkeys, do they eat it? Have you tried a different feed? Like Purina Flock Raiser? Or any other feed for that matter? Can you try some scrambled eggs? If I have one feeling poorly, I will offer them Quacker oats soaked in warm water, a touch of molasses and 3-4 eggs, raw, mixed in. They will usually go wild over it and eat it right away. It is possible that there is something wrong with the feed. Does it have any clumps in it? Does it have a moldy or musty smell? I'm not saying it does, I'm just trying to cover all of the bases here so nothing is missed.
