I have a hen, 2 to 2.5 years old. Three days ago she started acting broody but no egg came out. Her tail was up. When I took her out of the box, we found that she was missing most of her breast feathers and the skin had red streaks in it. The area smelled like infection that permeated our clothing. I do not have pictures yet but am hoping for advice based on what I've written. We have put her in a hospital cage, administered vetricyn spray and nutridrench. I went into her cloacal opening with a finger and felt no egg there. She has laid three poops with form, fairly large ones, didn't see any blood or worms in it. She is eating and drinking, comb looks normal. We also admined 200 mg of erythromycin (fish supply) in her feed. She has now been in the hospital cage 22 hours. I moved this to the shed as flies were starting to bother her. She's still exhibiting the "broody" stance, body spread out, tail up but hasn't laid. ETA: Just went out there again, gave her another epsom bath soaking the butt and sprayed her breast belly area with vetracyn. The smell is gone and she appears to have eaten most of the feed that I placed the antibiotics in. Checked her vent with a finger again and didn't find an egg in there. She almost immediately went back to broody stance with tail up once back in the hospital cage. What should I do next?
