I posted in the wrong forum, because I thought what we had was just a weird egg formation, and it turns out it is more serious. A "lash egg". https://www.backyardchickens.com/t/1076044/i-better-post-a-picture-of-that-weird-rubber-alien-egg So I should have posted it here. Now what? Antibiotics for everyone? I'd like to save those I can. Where do I get antibiotics, and how are they administered? I'm asking around on facebook for vets who may do chickens.
