This is my first year with babies that wouldnt eat. Ive never had any babies that didnt start eating within 2 weeks. I just checked my babies. The last one that has not eaten. Ate for me tonight. He is almost 3 months old the 7th of this month will be 3 months old. I went by the how to in that link I posted and worked great. Took a bit but did work. This male was hatched at 70g and is down to 45g so he lost a bit of weight. Stick with it if you get worried take it to the vet see what they say.
