Chicken sneezing and making weird sounds

[ChickCrazyWorryWort]

Today I got home from work all the chickens seemed fine when I let them out to free range. I went to see what they where up to a little later and heard this girl sneezing like I’ve never heard before. I also have never heard her or any of my chickens make the sound she’s making. A few of my chickens have been sneezing off and on but nothing like this. We have been giving the whole flock tylan 50 orally for almost a week now because of the others sneezing. She was never originally sneezing just read the whole flock would need treated. I don’t hear anything when I try to listen to her lung, but I noticed her crop didn’t feel very full. We separated her and tried to give her scrambled eggs. She started to eat the eggs but then stopped. She seems very active running around like the other chickens. I have attached 3 videos of her.

Just went and checked on her. She’s just roosting now not making as much noise. I think she more or less just spilled the eggs instead of actually eating them. I did add electrolytes to her water and gave her the tylan 50 a little bit ago.

I checked on her this morning and didn’t hear anything but it was sleeping. I have been home with her for about an hour now and I haven’t heard her sneeze or make any kind of strange sound. She never ate her scrambled eggs, but I just let her out of the pen (she’s been in all night and day away from everyone else) to free range with the others and she is foraging with them. She really seems completely so far.
