Hi Chicken Lovers I have had chickens for a couple of years, thus still a newbie. I get rescue chickens generally and have struggled w a high mortality rate. I've had several necropsies, but they generally have not linked the deaths; e.g., one had egg yolk peritonitis and and another possible Merecks. The chickens I generally get are alumni from factory egg farms (hence vaccinated) I know they have high mortality rates, but I don't want to contribute to their mortality by something avoidable. Fast forward, to present. I started weighing my chickens regularly because weight loss seems to be a good indicator of deteriorating health, maybe even before other symptoms appear. What do I know? Anyway, I have a rescue Legghorn about 3 years old who has lost one pound (down from 4.5 lbs to 3.5) since July 6. Also, she doesn't wolf down the foods she used to enjoy. She has been laying eggs like mad (pretty much daily). But had one egg today w/o a hard shell and one this past week that dropped on the floor of the coop. I decided to worm her, so she got Wazine 10 days ago and I'm about to give her Valbazen. Any other suggestions would be much appreciated. (I've given her a check over, and don't see any creepy crawlers, but I am probably going to bathe her w a dog flea shampoo just to kill anything). I've learned a lot from this forum, so thanks again for any advice.
