Iam having a very hard time raising call ducklings and would really appreciate any help. . First off for whatever reason my flock has been laying fertile eggs this winter. Iv been puting them in my sportman 1202 incubator and so far ruffly about a dozen or so have hatched, But i keep losing babies left and right. Inbetween age 4-10 days old, Shortly after i give them there daily water they will fade out, get disorientated & roll on there backs, Most have died there on the spot, While others have recovered only to do the same the next day before dieing. (I have 2 survivors and fell like its only a matter of time before they have the same faith) Broader Setup: 20 gallon fish tank, 75 watt bulb 15 inches high in corner (Light always on for heat) Gamebird Crumbles (non med), Water twice per day in a small enouf cup so they cant fit inside just drink from and Paper towels on floor. Water given is room temperature plain ol new york tap water that all my other birds,ducks & animals drink (never any problems). After the first few died i put the second group on tylan antibiotics for a week thinking they could be sick, That group lasted a week longer before they died, Again right after drinking.
