I recently was given 8 chicks bought from a feed store. All are bantams but three passed away. Two were extremely small and looked to be pulled from the incubator a tad early. I also forgot that you can't put foreign chicks around other full grown chickens which I stupidly did but I'm not taking the last five around my olders until they are older. The chicks eat like pigs then will sleep. One second they will be hyper the next they will be falling asleep standing up. Is this normal? And when I left this morning one didn't eat like a pig like the other four but he did get water and was a tad sluggish but was fine yesterday. If I go home today will he more than likely be dead?
