Buff Orpington not eating and is quite skinny - Page 2
Just another thought...... If you give treats and she is used to getting treats..... Perhaps she is super picky now.
I would offer her a little yogurt with layer feed mixed in. It may help get some layer feed in her that way. I also think making a small (very small) bowl of oatmeal on the soupy side and mixing some layer pellets in there couldn't hurt. I would of course cool the oatmeal and give it a stir to break up/dissolve the pellets.
