To be honest with you i don't remember the brand of wormer I used that was a couple weeks ago. I didn't give another dose due to the fact that I didnt notice any worms on the ground right after they would poop. We go through a 50 pound bag of feed every 2-2 1/2 weeks. with the last bag I was feeding 19 chickens. But since I bought a new bag I have sold 7 of them 5 being roosters. But I always make sure that they have feed in the container and water in their for them.
I have felt the keel bone and they are not a thin as they used to be. Besides laying around and being pale they seem to be fine.
I do have one hen in a completely different area that I am just figuring out has mareks. So I am not even sure what to do for her. This is so frustrating.
And I haven't noticed them being egg bound but I can go check again.
I wish I would have been warned about how difficult it is to raise chickens.
