My BR pullet got very agitated and started "growling." My EE pullet became inactive, and stood around stiff as a board, not a peep out of her. So watch for a change in normal behavior. I did not see squatting. In not quite a first week of egg laying from these two I have gotten 5 lovely brown eggs and 1 green one, plus the first EE egg was broken and eaten, which is apparently not that uncommon for young pullets. They were not on layer rations yet so likely shell was weak and she did not lay in nest box. I switched to layer and added calcium source. For sure, these two did not seem to know what was going on with the first egg or what to do but now they are in the groove and both laying in box.
