Hi, thanks for reading. We are on day 8 totally new to chickens. We have pullets who are now about 16 weeks old. First one, now two, are acting very weird. Not really eating/drinking, laying in shade, lethargic. I took a video of one of our girls but I can't get it to load here. Basically noisy mouth breathing and then a large squawk about every 20 seconds. Any suggestions as to what is going on here? Thanks so much for the help in advance.
