My girl gets All Flock feed and occasionally protein treats for the molting. And yogurt every so often but not even weekly. Now would mating do this? I ask because she is in a pen with my SF roo but none of the other two ladies in the same coop have a red bum area. Any info is appreciated.A very common cause of swollen abdomen is fat accumulation. If left to develop over time, it can result in fatty liver disease and other complications leading to death.
I suggest you examine the diet of these hens and determine if they may be overindulging in carbs in the form of too many treats. The treatment is to cut out all carbs except for what's present in their commercial feed.
