Is this a symptom of moulting or is she sick?

Hi, I have 2 chickens who are moulting but also doingvery liquid  poo's (clear watery liquid with some solids in) ...is this usual during a moult?
 I took one girl to the vet last week and he discovered a flesh egg which he removed and gave antibiotics. Although she's perky, he's diagnosed her with hardened intestines due to a previous infection and it's probably terminal..we're keeping an eye on her and will take her for her final vets visit when she seems to be suffering which she's not at the moment.  My problem is that my second chicken is displaying similar symptoms...full moult, reduced appeitite, hunched, sleepy and watery poo.
Does anyone else recognise these symptoms?

Hi joyfull  I cant remember exactly but prob 3 mths ago with vermex - worth doing it again do you think?
