I got my big female pied and she went 3 weeks before she finally ate for me ( I got her at about 1300 grams) it was nearly another month after that before she finally pooped for me, and when she did like an inch of her poop was almost like cement, it crumbled it was white it wars like rocks. I think with her being shipped to me and not being comfortable in her new home and everything mixed together had something to do with it. now that she got that out of the way she seems to be more regular. my other bp's id estimate once a week, hatchlings a little more than that maybe 2 or 3 times a week.
