First thing -- on this WOE you are allowed to eat the chicken skin -- in fact (as long as it is not breaded) it is better if you eat the skin because the fat will help you lose more weight.
Now, I will try to reassure you that your weight will swing up and down to a certain degree each day. Water weight, salt intake, 'regularity (ahem...), how close your TOM is, etc. will all impact the weight. In my experience, I have had this weight loss pattern:
new low , up two pounds, down one, up one, back to low, up one, down three to a
new low , up one, down one, up one, down two to a
new low, down two to a
new low, up four, down two, down one, etc.
I keep track of the new lows -- which keep getting lower! Some people on this board wiegh every day and then keep track of their weekly AVERAGE weights to account for the normal variance of our body weight.
Your weight swing seems pretty normal to me -- don't give up.
