My three little girls are all 20 weeks old. They switched to layer feed after 17 weeks. No eggs yet but one has me worried. I've raised them from chicks and they have always been handled. Ok they are total rotten if truth be known. Cluckey, a Blue Andalusian, has been acting very weird the past three days. She began squatting a week or so ago. Her comb and wattles have increased in size and is really red. She has been the only one interested in the nest box since it became available. I checked her vent (larger than the other girls and moist -no mites or fleas) and hips (2 & 1/2 of my little fingers fit) yesterday. No lumps in the abdomen that I could feel. Her eyes and nose are clear with no drainage. Her behavior has me worried the most. She is my baby and is normally right under me when I'm outside. This morning she ate only small amount scratch. She is still drinking water and eating grass and feed. In fact her water intake has increased. Now she is getting away from the others and walking around. She will still run if a bug presents itself but doesn't go as long as she has before. Her poop is runny (no worms or strange color) but I'm thinking it's from the increased water. She is just normally with the others and when they notice she is missing they go nuts. Is this normal for pre-egg laying behavior or is she getting away because she is getting sick?
