My girls seem to get agitated when I clean out their coop especially the nesting box lately. Last week two of them jumped on my back while I was in an upright position to get to the box and the other ran inside the coop. Today, two jumped up on the edge and was staring at the box, me and started acting a bit "off". Fluffy laid an egg that I had placed on a higher portion of the coop and jumped up to get at that. I was afraid she would crack it and took the egg, all 3 flew down on the ground and displayed more aggressive behavior, Fluffy and Dory both pecked me and behaved like they would peck more. I talked to them sternly and lightly poked Dory on the back and they went back to eating. Is this normal behavior?
