My White leghorn is very ready to lay her first egg, squatting, red wattles and crown, gets in nest box to sit. Some of her coop mates have already laid a few eggs. This morning she has started squatting a lot more and I noticed when cleaning the coop this morning their was a blood blob in the nest box, poop board and on the floor. It is like clear snot with a blood blob inside about the size and length of my pinky finger. She is drinking but not pecking about like her normal nosey self. She is my greeter hen but is not greeting today. When she goes out in the run she sits and if inside the coop she sits on the floor or nest box. What could be wrong? I am really worried but I know she could be having a hard time with her first egg. Just want her to feel better.
