A couple of days ago, I heard one of my chickens make loud sqwaking noises, I had never heard them make before. Alarmed, I ran out side to the run. I see all my chickens except one, my australorp. So I search for my australorp. I find her in one of the other attached runs. She is sqawking up a storm and trying to go through the chicken wire to get back to the flock instead of using the doorway 2 feet to her left. I pick her up and take her to the rest of the flock. She calms down and is fine. Then a few hours later, I'm in the run and she starts signing the egg song. I think "Whoohoo! Eggs are on the way! No egg that day. No egg yesterday. I go out there this morning, and I found the nest box had been disturbed. So I looked in it and find only the golf ball. Then I look on the gorund and there is a small brown egg! So I go to pick up my australorp to look at her vent to see if it was indeed her who laid it and she bit the dickens out of my hand! She did not want to be touched. So my reason for posting, If it was her who laid it, is she just hormonal right now? She has never bitten or pecked at me before When is it safe to incubate the eggs? I saw a bulls eye in the one I found today, so my little guy is doing his job.
