I lost one yesterday and have another one acting this way today. Find them in the brooder laying on their side. Unable to get up and move around normally. Hunched up, mouth gaping a little. Can sit up when I pick them up and put them back in. Dead within 24 hours. They are on medicated chick feed. Other chicks act normal. Seeing as this is the 2nd to act like this, worries me that the others will cecome sick as well. Any ideas or advice welcome.
