You are welcome. I didn't mean to get into a fight over anything. I just want to give the best advice that I can with the information given. The only way to know what kills something is to have a necropsy done. Since one wasn't done on the rooster, we will never know. I don't believe that birds need extra vitamins if they are given a well-balanced diet and are healthy. Because of the Marek's, I do give vitamins and electrolytes daily to try and boost immunity. I've lost 30 + birds to date and if I can save just one person from this heartache....
No I'm glad you mentioned other things, I have all my chicks from this year in the same pen and will have to start over if they all start dying. And I looked up every disease when the rooster got curled neck and started not being able to even stand. He kept falling to side. He would eat and drink and poo looked normal also.
I feed them game bird grower, cracked corn and scratch. Throw in grass and give them mealworms so I thought I was giving them enough. Maybe I need to give more vitamins? I wasn't giving them any until someone said I need to, this is my 1st year owning chickens so still learning.
But I am hoping she is OK and gets better. I will be so upset to loose her, my husband even said tonight " she's the nicest one".
