Hello, My favorite 16 month old EE hen has a problem. Last week she laid an egg with a chalky clumpy film on it. She didn't lay it in the nest box just in the coop. She has not laid an egg since and she has a poopy butt. She was laying a green 78-83 gram egg 6 days a week. I think that is jumbo sized for a chicken. She runs in the yard free ranged with the other. She still eats, drinks and poops.
