I read somewhere that you can put a dish of sand in your brooder so the chicks can learn to dust bathe and it will give them something to entertain themselves. I washed out an old roasting pan that I had been using out in the garden, filled it with fresh sand (the washed play sand) and put it in their brooder. Our three-week-old chicks have been playing in it - but they've also been eating it. They have a container of "Chick Grit" in their brooder, so I'm not sure why they need to eat so much sand. They're eating their food, too - but I'm just wondering if they can eat too much sand. Silly as it is, we have been having fun cracking jokes about seeing our three chicks in a roasting pan! They sure do look cute playing in that pan.
As much as I really wanted to buy that Cedar Play House and convert it to a coop, we've decided to not take a chance with the cedar. I'm pretty sure we're going to go with this design I put together.
