I have 9 chicks in the bator and my sex-link theory has some major holes. I actually have 3 roos in that pen and I assumed the Welsummer was the top roo because he chases the other roo all over, but I think the Split Black Rock has been sneaking some in on the side, because I have a lot of blue chicks. Or maybe they have an agreement I wasn't aware of regarding whose hens are whose. Not a single chick has hatched yet with the classic Black sex-link pattern.
The chicks are still really cute and the hatch isn't over yet. I'll have to test my theory again when I get those extra roos out of that pen.
I've been busy, busy, busy over the last 24 hours, yesterday I cleaned the whole house. Today I've run a bunch of errands and vacuumed out my van. Now I can enjoy myself guilt-free. I'm pretty tired though, the dog woke me up by vomiting on my nice clean bedspread
