Ok, I bought my 2 SLW eggs to hatch with my other 18 coming in the mail, but I'm not sure when they are due to arrive this week. I don't want to wait too long on these eggs.... So, I have 2 broody hens, but they've been broody for about 4 weeks already. (silkie and silkie/cochin mix hens) I've NEVER done the broody hen thing. Should I go ahead and place the bought eggs under the girls anyway? or should I risk it and wait for my other eggs to arrive to place in the incubator?
