I hatched some eggs back in August resulting in a single chick due to a massive temperature spike. This one and only chick lived in a brooder in my room for months, knows his name, follows me, and now clearly doesn't know how to be a chicken. He has spent the last 3 months with the rest of our flock and the other day I went out to find him with frozen feet! the poor guy apparently didn't get the picture of how to use the coop and had feet frozen like ice cubes along with the tip of his wing. So I brought him inside defrosted him and he was doing much better. Because of the extra time I am spending with him I realized he has lice/mites and needs to be treated. I have been unable to start treatment (on him or the others) and he seems to have started to go down hill very lethargic. Wouldn't eat/drink then causing dehydration on top of it all. So with limited resources and information I have given him 1cc of red cell, force fed him 18cc of electrolytes, and fed him a handful of layer pellets/crumbles and a scrambled egg. He has shown improvement , eating on his own but is still refusing to entertain the idea of drinking water. I am going to the store tomorrow to buy stuff to treat him and the others for lice/mites. What else should/could I be doing for him?
