Like I mentioned before- scrambled eggs and honey to stimulate him. Yogurt is also very good along with wet chicken food and/or cooked oats. You are doing all you can, now it’s just a matter of patience and prayer.❤️
Rice is not too good, they have a hard time breaking it down. I would give him scrambled eggs, oats, some honey if you have it (always perks my birds up) and occasionally some tomatoes and other veggies.
