Hello! This is my first year raising chicks and ducks. One of my chicks is not feeling well he is the runt of the group of six chicks and two ducks. He is usually quite active and full of energy but we've recently had a bout of bad rainy weather and today he just stands around in one spot and does not eat with the rest. I did change their diet just a bit by giving them Bird seed mixed with their chicken feed and also fed the ducks some popped corn. I don't know if my little chick ate any. He's like a little chicken zombie right now I moved him from the others and he's gone from standing in one spot to just sitting there. All the others are quite healthy and energetic he has always been the smallest of the bunch but he has also always been the loudest and ate and drank and been a normal chick. We have had them for approximately three weeks now and they all get along well in fact the little chick sleeps between the ducks. Any clue as to what to do? Thanks.
