I have had my 4 ISA chickens for 3-4 months now. I bought them as pullets. Everything has been going fine until about a week ago. Every morning I find a crushed egg on the ground below the roost, which appears to have been eaten. Yesterday i found an eaten egg plus a cracked egg and a perfect egg below the roost. It appears to me that 2 eggs were dropped from the roost and the third decided to lay beside the first two. This morning one empty shell again. I have searched this forum and this does seem to be a common problem. I will put some straw or shavings below the roost, hoping that if the egg falls and does not crack they might leave it alone. Any other suggestions or tips that anyone could give me would be greatly appreciated.
