I have never had a chick die after being hatched. I hatched Cream Brabanters from eggs last April. Had a bad hatch out from eggs of this stock and of the three who survived i have lost one today (2weeks old) with classic symptoms of AE. Of the remaining 2, 1 looks iffy and the other is vigorous. Any luck with vitamin therapy?-should I not hatch any more from this stock? Bummed- never had to deal with anything like this before! the Adults are healthy!
