I just lost a baby chick that seemed to be fine and I suspect the pine shavings may have contributed to some degree. I also have another chick that developed a raspy chirp and a crackling sound with her breathing after being in my brooder for a couple of days.I noticed these shavings have quite a bit of dust, I bought a different brand this time. Ive been reading pros and cons, I never had problems before with pine shavings but to be safe, I removed them and put a towel in for now and will buy some sand tomorrow. Can anyone give me some input on this? I read on another website that pine shavings could be bad for chicks. Im pretty bummed out about losing this one......Thanks in advance for opinions.
