I have 6 silkie hens and it seems like when 1 (or more) go broody, they all stop laying?!?!?! This is the 2nd time that they have done this. Is this "normal" for the breed? Is there anything I can do about it? I don't "need" them to be broody since I have an incubator and I sell hatching eggs. Them NOT laying all because 1 thinks she needs to hatch some pine shavings is really putting a damper on my hatching egg collecting!
