Hi everyone need some help new to chickens and not sure if this is normal. She is a barred rock I also have two reds and a golden wyndotte all about 24 week olds and two dominiques 4 month olds. She has been very lethargic not walking around much just laying there and keeping her head tucked in, not getting up to roost at night looks very bloated. Had to clean her rear side a couple times runny green poop. about 2 weeks ago stayed in nesting box for 2 days and did not want to get out just stareing off into space. i thought she was going broody have there was a egg under her, but only been getting eggs for a couple weeks. Took egg away and seemed to go back to normal then started this yesterday she is eating and did go out to free range today . About three weeks one of my 4 month old has similar symptoms but had gotten pecked really bad to back of neck from rooster I thought it was from the peck but symptoms may have started before and then ended up getting pecked we ended up loosing her. any advice would be greatly appreciated.
