Good evening, We are new on here and new to chickens. We have 3 Warren pullets around 9 months old. Obviously been very worried with the recent bird flu outbreak but we seem to be ok with this so far. When cleaning then out we have noticed the they have had some lose poops some have been just water. This morning we noticed that one of our girls has been puffed out and stood still in once place and we have found some dark green poops with a think moosey consistency. She is the biggest of the group and normally very vocal in a morning, we have noticed we have not heard this recently. And picking her up tonight she has lost a lot of weight now smaller than our smallest hen. We have read some online posts of pop and can see that worms could be and issue we had been using some digestion pellets. She seems.to be eating okay but keeps standing around puffed up. Please can someone offer some advice? Thanks in advance.
