I have six chicks and they are about two weeks old . One of the barred rocks is acting strange and was under heat brooder all day.... she was super active when she first arrived but now when I took her from under he brooder (eco glow) she just stood in the middle while the other chicks ate food or drank. She was just standing there not moving. I took her out with another chick and noticed her try to hug and cuddle with the other chick. I put her back under heat brooder and she walked in. I’m hoping she is fine. Any thoughts? Not sure if there is something wrg. She was sooooo active in the beginning and now all of the chicks are getting more active and she slowed down tremendously. no pasty butt btw. Any thoughts?
