Had 5 chicks and 2 ducks all 3 weeks old. Kept in separate areas. A chick died last night suddenly. I was at work but my girlfriend said they were acting normal. Now today, both ducks go into spasms and die in my hands within minutes of each other. So while I take the passed ducks outside, two chicks die. Two others now look lethargic. Earlier today I had them out running around and they looked great. Now I only have two chicks left and I'm not sure if they will survive!
