Oh, definitely a major drawback. Painful for us to pay for DNA-sexed Silkies but there's no re-homing roos in the city.They are a lot of fun.
I am tempted to hatch more silkie / Polkie eggs - except for the fact I would get Roos - so that is a huge deterrent to me.
The only time we ever had true baby chicks were the auto-sexed Dominique chicks where we could pick out the female babies from the feed store bin.
