some tiels don´t mind or sit ont eh eggs until a considerate amount of eggs usually 3-4... this is so they all hatch around teh same time....

this is not that good... but you can increase fatty "junk" food for her to gain weight... sunflower seeds... they love them... and are just like chips and donuts.. haha...

let her have also some pasta and bread... and include a few green veggies the darker the green the better.. (just not too much lettuce as it gives them the runs )
