I'm sorry to be a downer just needed a little support. I hatched some wellsummer eggs last Saturday 5 hatched but one had something neurological wron with it just layer on its side and would spin around. Tried everything vitiamins putting her in s sling feeding her from a dropper 4x per day. She wasn't improving. Decided it was time to let her go. I just put her down and feel awful. It's terrible how attached I got to the little bugger in a week. Rooted for her to get better. Chickens get you right in the heart but I know it was time.
I am sorry to hear this, it is never easy to lose a chick. what you did was incredibly humane, it takes a lot of strength of character to put an animal down. I admire you.
