I have 2 black australorp hens and about 2 weeks ago neither of them had laid an egg in about a week because my brother was taking care of them. 1 hen started laying again after not having had laid an egg in about a week and my other hen still hasn't laid any eggs since about 3 weeks ago. I haven't changed anything during or around when they stopped laying. The hen that's not laying has seemed a bit cranky. I always bug her and she hasn't been letting me too much lately. Also she's seemed a bit tired, even her clucking. Someone please help me find out what's wrong because I have no clue and I'm a little worried if there's something wrong or not.
