I started a breeding project this Spring, to add another generation to my Dominique flock. Had incubator issues and sadly only netted two healthy chicks...both Dom roosters. So I went to Murdochs and purchasd four female chicks advertised as as laying blue and white eggs, Ameracaunas and...
I have 32 Domnique chicks, 3 weeks old today and tomorrow. Several of them have this thin vertical line that looks like a wound (dark red) smack in the middle of the upper lip of their vent. Anyone know what this is?
A Google search didn't turn up any clues.
