So I put new bedding down for my chicks and when I went to check on them all of the bedding was kicked out of the housing I'm keeping them in. I also noticed they were doing something strange like shaking while laying down then they would kick their legs out like theyre scratching. I tried to attached a video but I can't. Just want to know if this is normal or if something is wrong. They're Easter eggers. And 2 weeks old
