Alright, about four months ago when my chickens were dieing when they were 3 months old. I had 18, then about half of them just layed on the ground and wouldn't move. My mom thought it was because they were too fat to get up. But their legs didn't move and were very reluctant to move at all. Then they started dieing one by one. I just read something that talks about Chicken cancer and how it paralysis them and they are weak. Their poo was runny and kind of green sometimes if i remember correctly. They would flap when i can near. One of them was trying to stand, but couldn't, his wing was kind of bent, i would straighten it but it would just go back. To try and help them i would put them in the sun on the grass and put low water troughs around that they could reach and food near their heads. I also got this medicine that you put in water and it didn't help either, i saw them drink it. They did not have any visibal injuries or broken bonesexcept for the rooster and his bent wing. My question: Did my chickens have cancer and will this affect the surviving flock later on? What should i do about it? A couple have died since them, but none of the same symptoms. They just keeled over in a corner. Do you have any advice?
