I have 8 ringnecks that are about 3 days old. The last one to hatch came out w/ bad legs but has been improveing everyday. Today I heard one making a loud cheeping noise so I went to check and the one w/ the bad legs now has his vent pecked to where it is red and fleshly but not bleeding. What can I put on it, if I should put anything on it? Can I put him in the incubator for a few days, there's nothing in there right now?
