so I've got two chicks that have spraddle leg. they have improved, but not all the way. one is hopping but not putting weight on the off leg. the other is getting stronger but has not figured out how to move much yet. He manages but it's very "floppy" i've got them hobbled and am fixing to try making their feet flat to see if that helps. they have vitamins in their water and I believe there is a little bit of probiotics in those as well.. How Long do I give them to get better? They were born Monday evening. and is there anything else i can try? Thanks for any help!
