Hi there! Yes, Taco and Ecko are very close in age - Taco was hatched on Feb 19th.
I've tried some brocolli, bananas, peaches but no luck yet - he seems to be a bit of a millet slut - I know it's not great to give him a constant supply so I limit the amount but he roots around all day looking for pieces. Will try your mix and see what he picks out - I do know he loves hot red peppers and peanuts.
Grocery shopping should be fun!
