Hi, 👋 (I am new here as well!) My babies are about 14 weeks, and were introduced to veggies including sprouts during weaning. I’d say they’ve been eating them as a regular daily meal for close to about a month (I’d have to check exact dates) however, they were introduced to them to pick at or play with at will during weaning. You could even offer cooked veggies - just make sure they aren’t still too hot as they don’t know the difference and can suffer internal burns. Cooked long grain rice or wheat pasta they can have in moderation (I say that because my 2yr old male would stuff himself with a whole bag of soft warm rice if I let him lol). I wouldn’t worry yet, it is perfectly normal as another poster said and it could be several days before he really starts to tuck in at meal times. Check feed dishes in morning as well because he might be nibbling at night. You could also leave the feed directly on a clean area of the floor or in a paper cupcake wrapper, so that he can literally stumble across it in case he’s not wanting to explore yet from being in a new home. Good luck and enjoy your new feathered friend! You’ll figure each other out in no time!
