I am so sorry he/she passed. I get attached the the little ones so easily. I find painting a rock for my passed birds helps me.I wanted to update everyone who so kindly answered my questions and rooted for us: maverick didn't make it. i'm a bit upset that i kept him suffering but i really wanted him to have a chance.
but we do have a healthy and insatiable flock of 5 day old ducklings that are a pleasure to watch! i can't wait for the weather to warm up and bring them out to the orchard!
again thanks to all of you, your responses meant a lot really helped us calm down and to stop googling worst case scenarios
