Hi, I have three young Isa Browns that lay an egg each per day. Two lay in the nest box but one seems to lay while sitting on the roosting perch. The egg is on the ground (in the poop and dirt) same place each morning, sometimes cracked. There are two nestboxes in the house but the girls only use one. I have put two plastic eggs back in the second nestbox as I think it is the chook at the bottom of the pecking order laying from the perch and thought there might be a queue for the preferred nestbox. However the egg on the ground is often the coldest so perhaps is laid first. (Is it that she just can't wait to get off the perch to lay!?!) All three were laying in the nest box until about a week ago. How can I break this chook's bad habit?
