Okay so my boyfriend is supposed to be picking up my silkie chicks today after work (fingers crossed). They will probably be anywhere from 3-5 weeks old (when I first talked to her she had chicks 2-4 weeks old) so I wanted to know if this kennel will be a good brooder: It has ventilation holes all along the sides and back, but not big enough for a chick to get out of (or my kitty to get in). I could lean my tortoises ceramic heat emitter to one side so they can stay warm. How old will they have to be until I can put them in their coop? Also, would they be okay over night without food until we can go get some tomorrow or is that no good? And one more thing: Can I use the sand from my back yard as grit, and can I use play sand as grit? I used to give my quail play sand as something to dust bathe in and use as grit, they never had any problems with it. And could anyone point me to a place that has week-by-week photos of silkie chicks growing up? Sorry for all of the questions and stuff!
