I just can't seem to keep them from kicking wood shavings into their water. It starts to smell and prevents them from drinking. I have to unload the waterer several times a day. I tried putting the waterer on a tray that doesn't have any shavings on it but they still manage to kick it into there. Any ideas? Right now I have a red watering jar lid attached to a jar filled with water. The four chicks are 8-10 days old now...do you think their ready to come out of the 10 gallon fish tank and get moved into a bigger bird cage? The heat lamp would still be there but the temperature may not be as high.
