I was referring to you question on
this thread. The person was saying to put air in a chickens lungs and watch it. You asked about that....I was replying to you. That person has not been on but ONE TIME period, probably a troll. I provided you with a video of how the respiratory system works so you could understand that very unlikely you would "put air in the lungs" without doing some major damage.
You have questions? If you do, then starting a post of your own can be helpful to you, you can ask specific questions and hopefully will get some replies. It seems like
you are dealing with some illnesses/conditions and need extra help, so having a thread of your own, you can address those concerns.
As for lesions - well, lesions, mucous, yellow or white pasty material, sores inside the beak.
