I introduced 2 new birds to my flock and they had coryza, I didn't know this and put them in with my others. I have since culled those two out of the coop. My birds have been on Sulmet for a week and some seem to not be affected at all. But another one started wheezing and sneezing yesterday...
I have two Red stars and some others. One of my young Stars laid one nice sized egg but it had some blood on the shell. ever since she has tried to lay everyday but with no success. Can anyone give some helpful advice.
