Call duckling not growing.

[ruralmom]

I, woohoo, hatched out 7 call duckling on May 25th thru the 27th. All went well except for the last one. it was a bit slow and left in the bator an extra day to get strength and dry well before going in with the others. All hatched within the two to three days of each other. Well Benita, Benny for short is not growing, she is the last one to hatch and she is not much bigger than the day she hatched. I am now worried for her safety due to her sibling are twice her size and she gets cold so easily. Heat lamp still on and she usually sleeps on everyone. of course, food is game started, the kind with 28% protein. I have tried to soak the crumble and she does not like it and I give her all the mosquitos I can swat off of me. Is there anything else I can do? Protien shakes, duck lettuse style? Any suggestions very welcomed.

Have you tried feeding her watered-down egg yolk (from a hard boiled egg)? Or perhaps mealworms? You could also try a mixture of honey, plain yogurt, and poly-vi-sol (without iron) infant vitamin, but the yogurt shouldn't be fed as a major ration long-term.
