Yea, she's a big girl. I have to keep her in a tub halfway down the rack. She got heavy constantly pulling her out of one of the higher tubs.
Every female has a chance to get that big, it's just a matter of how they are raised. This female was originally a CH that someone bought as a pet. They had her for years (never bred) and gave her up to a local pet store. I picked her up in 2009. It also helps that she only goes off feed from ovulation to a week after laying, she's an absolute pig the rest of the year.
