I am considering getting 3 more chicks this year. I already have a small flock of 5 chickens, and I have sand in their coop. When I made the transition from straw to sand my chickens were all 3 years old, fully grown and matured. The sand has been going well with no adverse affects to them. But I'm wondering, if I get chicks, how would sand affects the chicks when I put them in the chicken coop? I've read that using sand for chicks isn't recommended because of the dust that the sand may put off, but I think that's for more younger chicks. Even so, I'm concerned that even though my sand doesn't put off a lot of dust (it's construction sand, so it isn't super fine and dusty) that what dust it does put off will still harm a young chick approximately 6 weeks old (old enough to be in the coop). Does anybody have any experience with this?
