I've had females do this before when I had them in a separate tank to long with fry she recently spit. As stated above, she will spit them or swallow them, no need to do anything. Although if she's in a tank with fry, remove her or you could wake up to an almost empty tank. Again I had a female OB do this, kill almost all her previous fry after she dropped a bunch of unfertilized eggs. Many underestimate Female Cichlids, in my experience they are the only ones that have killed in my tanks. Mama Bear lives in them too.. lol
