We have some 1 and 2 week old chicks and all have been vigorous and healthy so far. For the first 2 weeks I used newspaper with paper towels on top for bedding and had no problems. Yesterday I switched to pine shavings which the hatchery and the farm store both highly recommended. Now I notice that all this morning 1 little chick keeps opening and closing his beak and his body looks like it's kind of heaving. Sort of like he's standing there gagging, but nothing happens. I dip his beak in water, and he swallows a little but keeps opening and closing his beak. The only thing that has changed is the bedding so is it possible that's the problem? I was told the pine shavings were the best thing!
