One of my 3 day old chicks, doesn’t seem to have the energy of my other chicks and when I watch her breathe while she’s sleeping she seems to breathe at a faster rate. Is there anything I can do? They have water with electrolytes, have food, and are in a large box with temp that ranges from 100 on one side to 80 on the other side. They walk all over the box and don’t seem to avoid any areas, and I often find them sleeping in the warmer section...they sleep all over, sometimes separately and sometimes next to each other. I have the light only pointing about half in the box, because otherwise it gets too hot. It’s about 30” high. I’m using a 250 watt red bulb, and am wondering if I need to downgrade to a 100 watt? I also have a radiant heat brooder I can use, and can ditch the bulb altogether. I just wasn’t sure how they’d do going from a light to a different set-up, since they’re all used to the light.
