I noticed one of my Gold Star pullets (Rosie) was slow to eat the meal worms I threw out on Tuesday morning. She was stumbling to the right with her wing out. I got her separated from the others. She is still showing neurological signs and doesn't seem to be eating what I would consider normal. She is 11months old and has been laying since April. The strange thing is that we had a Buff Orpington show same symptoms last year at this same time. We thought the other 4 had hurt her. We were newbies. We did put her down after a few days when she didn't get better. Now I have found this site and I'm worried it's Mareks. Could it be botulism? The area where the chickens are was where the previous owners dumped all their trash. We have cleaned it up but everyday i pick up glass, metal, and plastic that comes up through the soil.
