I did a search on this site on Welsumers and found a thread that describes them as terribly aggressive. I planned on ordering 24 Welsumers and 12 White Leghorn chicks for a spring deliveery. Will they all co-exist without the Welsumers killing the Leghorns?? Also, are there any recommendations as to a good trustworthy hatchery to order my chicks from?? Thanks for any and all sugestions and help.
