I went out to the coop tuesday evening to close the chickens in. I found one of my chickens who is 5 months old making horrible sounds. I did not see anything in her throat. I gave her doxycycline that was left over from a previous chicken. Also gave her some water by syringe, and nutri drench. I kept her in the house and watched her closely. Yesterday morning she was doing fine. No more noises and drinking and eating fine. She is very upset with me that I still have her in the house. Does anyone have any idea what this could have been? I'm trying to decide if I should put our back outside with the others.Because she is very stressed being alone... Any suggestions or thoughts would be very helpful.
