Have you given the chick some coconut oil? If not, chill slightly so it's firm and measure out a teaspoon full. Break off small slivers and slip them into the chick's beak. Very gently massage the crop to get the oil moving down the digestive tract. This is the proven remedy for constipation. You'll know it's worked when the chick passes a large turd. Waiting too long to treat with oil can result in death.I know this thread is old, but @minaayindra , did your chick recover? I have a chick going through something similar for the past 36 hours. I'm able to relieve the chick by soaking it's butt in warm water and it can pass some waste, but it is still struggling. I'm continuing to support it because it is eating/drinking well and really seems to have a will to live but I'm concerned that this may not improve.
