I let my Dwarf Fischers go free range every now and then. Recently I noticed she was biting the calcium buildup from the edge of a flower pot. I freaked out a little and pulled her away and put her back in her enclosure. I was worried she would get either too much or too big of a piece. Then I thought that in the wild, maybe she would do something similar. So now I'm thinking she nay not be getting enough calcium from the dusted crickets. I know she shouldn't get "too much" calcium, but I wonder if she will just quit biting it off the pot when she's had enough. What do you all think? By the way, she bit it 3-4 times and then walked away and went up to the top of the planter. So it appears she isn't hogging out on it. This calcium is from our very hard water, which is filtered prior to watering the plants. It seems to me that it would be clean and safe. It made me think of when I had a Budgie (Parakeet) a long time ago, and I'd put a Cuttlebone in the cage. The bird would bite and scrape away at the Cuttlebone in order to get it's calcium supply. The birds always quit when they had enough. So I'm thinking my little girl cham is practicing safe calcium consumption. I'd appreciate any feedback on this.
