My 16 week old pullet was acting strange last night when she was in the run. She was in the corner with her tail up. Looked like she wasnt feeling quite well.. After a few minutes, she laid an egg with a very thin shell. The other girls were at it right away. I scared them away from the egg but it was too late. Ten minutes later she laid an egg with no shell. I have seen her lay in the nesting box and produce a small egg almost every day for a week now.. Is she ok?
