thats good. Wish I could say that , one of mine went lame and couldnt figure out why he wasnt getting better . a friend suggested worming them and it was disgusting. I dont even want to touch him now. LOL I dont have very good luck with colorful chickens.
What kind do you have ?
I dont know any thing about newcastles. I am glad they are improving for you . even if they still have a way to go. Did the vet check the poop for worms while he was at it ? green poop=starvation. I have never seen the yellow.
