i introduced 2 new, approx 14 wk.old, white leghorn's last month to my 26 wk. old ISA Browns...the Browns are still going after the leghorns, the leghorn's don't look like they have grown any in a month...I'm trying to feed the leghorn's separately .... Any ideas of what to do? The only time they don't bother the leghorn's is when I let them out to free range...I know they have their pecking order but I thought by now they wouldn't be so aggressive!!! Help! Thanks!
