So lately I have been seeing aggression in a couple of my laying hens when I go to get eggs out of nest boxes. I have been using the absence of each hen when they are out eating as a sign they are in the coop laying. I have had 2 of my hens anytime I go in to get the eggs start talking aggressively and a couple times biting. My other hens do not do this. I left the eggs under one to see if she sits on them through the night and parts of tomorrow. I haven't dealt with a hen incubating before so do not know the signs of them wanting to sit on them or if they just dont like me there when they are in the box.
