So, last week, I went out a little earlier than usual (to let the chickens into the run) and was surprised to see projectile water being spewed from the mouth of one of my Buff Orpingtons. She and 3 others are now 9 weeks old and were added to my existing flock of 14 week old Australorps over a month ago. The Buffs have been a stressed mess as they didn't accept them easily and still peck at them (and chase them away from the food). I thought it was sour crop but she does not have an enlarged crop, even now. She is acting normal, no more vomiting, so am questioning myself - any advice? Is this not sour crop? is it just stress from all the bullying? anything I should be doing?
