I've had 2 chickens for a week. They are making this sort of squealing sound often. Does anyone know what it means? Are they scared? I recently set up a bigger run for them. Are they not being fed enough? I noticed lately when I toss them grower pellets, they are extremely aggressive in eating them. Maybe they're angry that their coop is dirty? Or that I used to have to catch them to put them back in their coop when they escaped? They are good at getting close to me when I'm about to feed them, but run the instant it seems like I'm going to grab them. Here's an example. The squeal happens in the second half of the video.
