I just got 15 chicks from my pet chicken yesterday. They only took one day to ship and they all arrived healthy, active and peeping. I put them in the brooder and all of them began eating and drinking right away. by late yesterday afternoon they all pretty much started becoming lathargic. Not making very much noise at all and laying down with their heads on the ground quite a bit. They have been that way since and are still like that this morning. Every now and then a few will get up and eat or drink and look normal when they are up but then they will lay down again. none of them really make a lot of noise. just some small peeps when they are up. no noise while they are down. Is this normal? The brooder is a 55 gal tank with cardboard on 3 sides with a red heat lamp. Temp does not appear to be an issue at all. I had a piece of material on the ground that had never been used. I took that out because I though maybe it had been treated with something that was affecting them and I replaced it with the straw that they had been packed in when they arrived. No change. They seem normal when I wake them up or they get up on their own. It's just that since yesterday afternoon and now they really haven't been up that much.
