One of my 16 week old EE's is staying real low to the ground. She is keeping her butt and tail feathers down and even walking with her butt low. she is drinking and eating from a squatted position. Her comb is not red....can't even see the wattles ( those are the cheeks right?) her comb is pink and small. there are other girls with much redder combs but they are not squatting at all. Should I be concerned or eggcited?
