Hello, Last week Penelope, my top chicken (of 2 adults) who normally is the one shouting to be let out (they free range the garden all day) was quiet when I went to open the coop. She had and egg of hers (which I assume she had laid that night/morning) on the floor of the coop which she was pushing around with her beak. I took the egg and she got out had a walk round then went back into a nesting box, put her head under her wing and went back to sleep. She pretty much did that on and off all day. This is the chicken who has been trying to crow (since we hatched out chicks at xmas) and usually sings the egg song very loudly!! I just though she was having a off day (do chickens get headaches?) however, since then she makes very little noise and has not laid an egg. Yesterday she clucked a bit, in fact both adults sounded the alarm and backed all the chick off when a rat came for a drink (having a heatwave here) - I threw a heavy rock and squished said rat (urg!! I surprised myself!) So no clucking and no eggs - any ideas what may be wrong? She does not squat if I try to pick her up either. She is well and eating/drinking scratching around otherwise. Any advice gratefully accepted.
