Hello all need a little advice... I have a hybrid light Sussex who is 4&1/2 -nearly 5 years old. This past week her comb and wattle have been darker than normal (almost purple at times) She shows no signs of anything no breathing problems etc but she is moving a lot slower (but then she is a big heavy girl) Thought it might be due to the heat recently (it's been in the mid 90s this past couple of weeks, very rarely gets in the 80s) she is drinking and eating normally. Gave her a treat this morning of crushed frozen cat food ( her fave) which she ate then got comfy for a rest. Here's a pic of her sorry it's a little blurry she never keeps still for photos as she just wants to eat the camera! She has recently been wormed (flubenvet powder added to food). She now has messy vent feathers covered in poop but is eating and drinking regularly. She still has the occasional dust bath and forage although does rest a lot. There is no sign of breathing troubles or mites/lice. Is it just her age do you think?
