My mom ordered 60 white orpingtons fro mcmurray, and we only have 18 left. When we got them home, yesterday morning, I got the heat lamps set up (one on each side of the stock tank) put lots of hay, to keep them warm, gave food and water and made sure the cats couldn't get in. They kept dieing so I'm like what the heck! So I brought them all in ( the 18 that are left. there may be more but they don't stand still) but they are still kinda dieing. 2 more just died. their symptoms are that they get tired, then they just sit there, I dip their beak in the water to see if their thirsty, nothing. Then they get soooo tired that they fall over and don't move, just breath. then they die! Any ideas on what this could be? I don't want them all to die, their just soooo cute ! Thanks in advance!
