Would they not eat the Quickcrete? Thats concrete mix right? If so, I would be very worried about that. I know my chicks tear up any sand I put in for them. I usually use the parakeet sand in a little dish for the first couple of weeks as a source of grit for them. I know chicks can impact their little gizzards if they eat too much sand.
Quote: 'Quikcrete' is a brand name, they sell many products, including many different concrete mixes...but what I use is called 'Fine Sand'.
It's actually fairly coarse as sand goes, and is washed, screened and kiln dried.
I did a lot of research and shopping on sand when mixing my own concrete for making concrete sculptures, it's very hard to measure the coarseness of sand unless you have a set of very expensive grading screens.There are a lot of colloquial 'names' for sand, but unless you can measure it, those names are often misleading.
To be absolutely clear, so no one uses a concrete mix for brooder bedding, here is a pic of the bag:
and here is a pic of some grains on a quarter to give the grain size a scale:
