Oh, I am so sorry to hear about your baby!! Let me just say tho, it is SO precious!! My goodness. How pretty! It might just have failure to thrive. But I hope with a little extra TLC that it will catch up on growth soon! I think what I would do is make sure it stays very hydrated. Wether that means dropper feeding it, or whatever you have to do. You could give it a couple drops of poultry nutri-drench or sav-a-chick to give it a little extra boost. Also, I would make up some scrambled egg every morning and give it to it. Raw egg yolk also works, but sometimes that can carry harmful bacteria cause it is raw. Make sure it stays nice and warm, and keep in eye on it with mama. Sometimes the hen can pick on the chick if it is not as healthy as they rest. You are doing such a good job, and keep up the good work! Oh and please, keep us posted!!
