Hello, so my sister in law purchased 3 chicks from a local farm supply store. We don't know how old they are or anything. We've had them in a homemade brooder with a red heat lamp. They've been doing fine but tonight I noticed the biggest one kinda freaking out. She's flying back and forth in the brooder like she's panicking. She is kinda panting it looks like, but she's not actually breathing through her beak just looks like she's panting because her throat area is going up and down...I'm sorry it's hard to explain. I am just so worried about them I want to make sure we're taking proper care of them but Google searches only get me so far. Any help is appreciated and I'll elaborate more if needed I'm just so worried about them, I care about them so much. We got them about 2 weeks ago and the girls at the store said they were probably 2-4 weeks old when we got them but they didn't seem sure on that and I believe they are bantams but other than that I have no idea what breed. Thank you so much. Also I moved them into a bigger container a few minutes ago to give them some more space and I just peaked in on them and they seem calmer but I only looked for a couple minutes because it's so late here I'm just too tired to stay up much longer. But hopefully they were just cramped and they'll be happier now with more room to stretch their wings lol.
