Is it normal for chickens to lose weight after you worm them? I wormed our girls with Valbazen for the first time two weeks ago and again 10 days later, this past Tuesday. I noticed one of our sweet girls seemed to be lighter than normal so I weighed her and she has lost 6 oz since the first worming. She was only 4.5 lbs to start with. The other girls are not losing weight so I am a little concerned. Other than the weight loss, she is acting totally normal, eating, drinking, laying, demanding to be held constantly.![]()
I saw no evidence of worms or parasites but our Vet advised us to worm our Buffs too since I had to worm our new Chocolate Orpington babies who were very sick and still in quarantine. I am hoping that worming our original girls when they didn't seem to need it didn't harm them.
I don't believe it does much harm. And better safe than sorry. Keep monitoring her weight. Is there much difference in what they were eating from the previous season? I don't know what vegetation you have in AL. Maybe she just needs a little pick me up.
