Hi, I have 5 wk old RIR that has been straining to poop on and off for the last 3 wks and more consistently for the past wk. She makes loud noises when she poops and it gets stuck halfway out and she will peck at it and continue to strain until it comes out. When this first started my local feed store recommended grit and adding probiotics to the water, this seemed to help initially by making the poop really soft. Now though she seems to have normal looking poops not too hard not to soft but continues to strain, her vent looks pink and swollen(at least much larger than the other chicks, ive attached pictures) She is otherwise happy eats, drinks, dirt bathes, runs and plays with the other ones. I will add she does always seem to puff her feathers out more than the other though. I am giving Dumor's chick starter, Dumors grit and using sav-a-chick probiotic in the water. Looking forward to seeing what folks have to say, just trying to be proactive and avoid a serious problem, remaining optimistic for now cause she otherwise seems pretty happy except when pooping. Thanks for your help in advance.
