I am new to raising chickens and I have no idea what to do about this bird. She is a Dominique, about 21 weeks old and one of 6. About 5/6 days ago I noticed she was kind of depressed. She sort of mopped around and stayed in the pen a lot. They have the option of free range or stay at home. We had to go away for 4 days so I loaded them up with plenty of food and water. When i came back she had this large lump on her throat. Being a newbie I did some research and thought it was an impacted crop so I gave her 1cc of apple sauce and 2 doculax. This was yesterday. This morning the lump is about half the size so I gave her more apple sauce and duculax. Since then i have re-read the article and discovered the crop is on the right side and this lump is on the left side and it has ridges. Just like an esophagus. What should I do?
