One of my silkies started laying a couple of weeks ago. She was going really well and laying 6/7 days of the week. They have a perch about 10cms off the ground and she has always insisted on laying from the perch. About 3 days ago she stopped laying and has been sitting on the same spot on the perch. I was worried that she was egg bound but then I thought that maybe she has gone broody on the perch??? I've seen her hop off a couple times to eat but she then goes straight back. I tried sitting her in anest box but she went straight back to the perch. Any thoughts??
