I thought I would share this with you guys since I've read about this happening to a few chickens on here. Today I noticed one of my roosters, Rambo, laying on the ground, on his side, unable to walk or pick up his head. His neck just kept twisting around over and over, like he was unable to control it. I read that this could be due to a vitamin E deficiency. So, I took some of the vitamin E liquigels, and poked a pin hole in the top. I opened up his beak a little with my fingernail and just squirted the vitamin E inside. I then took him inside with me, let him rest, and gave him plenty of water. Inside an hour he was completely back to normal! I'm not sure if this will help every chicken that this happens to, but its certainly worth a try. It worked wonders for my rooster. Just thought I would share!
