I have 2 Silkie/Cochin girls that have recently started laying eggs. Now all of a sudden they are sitting in the nest boxes & won't come out. At first I thought they were cold but now I know that they are being broody. They are sitting on NOTHING! I put my hand in to check for eggs & they lightly grrr & lift up for me but there is nothing there & they have not laid an egg in the last few days. They actually prefer to lay on the ISA browns eggs after they them in the morning cause I have been puting them in the cage at night. They will come out of the nest boxes to get their morning treats & then back into the boxes they go for the rest of the day. They want to sleep in there too. I was making them get out of the boxes but they just hop back in. Isn't this a bit odd to become broody in the freezing temps? What should I do? Should I let them go on being broody or should I lock them in a cage? Silly girls! Won't they be starving themselves or is their morning treat enough for them? Any help or advise would be greatly appreciated! Thanks!
