My Rhode island red seems healthy, eats well, acts normal. Quit laying a few weeks ago. Isn't moultung. Has laid a couple of undeveloped eggs in the last couple of weeks, and I can't really even call them eggs. They looked strange and had like a tail on them so to speak. I let them out occasionally to graze, the other chickens eggs are normal. Gave them some electrolytes to drink this week . No obvious signs of illness . Tks
