Hi, i am sure you will get answers soon, from better experts, than me.
She looks real healthy, on the video, you said she has been making these
noises, 5 days ago. So i do not think it is a respiratory infection, as months
ago 2 of my girls, fell ill with infectious bronchitis in which they were sneezing
watery eyes , gasping for breath. We bought 4 new POL and they brought the virus
with them. We were lucky the rest did not catch it. Our vet gave them antibiotics.
Thought we would lose one, as she could not open her eyes for 10days. But did not give in, and they recovered. Your girl looks way to healthy, especially enjoying that food. lol
Plus it has been 5 days as well. As for gapeworm, maybe but none of mine has had it.
The experts will know for sure here. All i know when mine had respiratory infection,
they would not even drink, especially eat food. I have 12 hens, and i can truthfully say,
when they see me coming, with the mealworms, 2 of them make a similiar sound to
yours, and that is before they even hit the ground. lol None of the others does it,
just them 2 and to us, it has been a sign their fav treat is on the way. But please do
not go by mine, but it is the same sound. We put it down, to it is their way, of showing
how much they are enjoying them. Plus they only do it with mealworms, no other
treats ect. So wait as i am sure you will hear from others, soon. I am sure you will,
keep a close eye out, for any changes. But to watch the video she is one healthy girl,
enjoying her food. lol Good luck.
