Ok I'm new to this , my first chickens I purchased 12 pullets from local feed store. The second day I unfortunately lost one little nugget . It was eating and drinking but not moving around as much as the others. I have had them 7 days now and my favorite little one is sleeping alot and not as as active as the others this is also the one that still has the embilical cord still there the bum is ok and it is pooping brown like the others the temp is about 92 in the brooder. I noticed when I just cleaned the space all the others where running to the opposite corner and this one was just staying put no matter how close I was. Whet I picked it up its legs seemed weak and it keeps going over to the corner and sleeping? Am I stressing for nothing or is this normal at times?
