I have a 1 1/2 year old RIR (feed store chick). She has been our skinniest hen, best layer with largest egg. Within the past 5 days, her laying has decreased to only one egg (yesterday) and the size is smaller. It is HOT (104) and HUMID here. I noticed some time ago that her feathers were looking picked on or just thinning out. I increased protein at that time and it seemed to improve the appearance of the feathers minimally. I started feeding feather fixer today mixed in with their regular Nutrena. She is now hiding under a bush, not running for treats, her comb and wattles are faded. She is typically very social and "talkative". Any feedback is appreciated. I'm thinking I need to get her something like gatorade for chickens or try to worm her. I only have 3 chickens and they are exposed to native birds trying to steal the chicken feed.
