These birds were between 8 and 9 wks. Some will begin to show stress with build up of fluid. This bird didn't have any fluid anywhere else and I hadn't noticed her showing any lethargy or cyanosis... though in another week or two she most likely would have shown some.how old were these again? I wonder if the birds so signs of stress with a heart like that? did they all have it?
She is the only one from this group with it, and the 3rd so far out of 15 that we have done in the last few weeks. The other two were early on and had grown at an outlandish rate and were huge for their age, which is why we chose to process them younger... neither was severe, but both had fluid starting to build up. One of those was showing signs of fatigue/lethargy and some poor color at times.
We also found it in an older roo we did last fall... so it is not just meaties that have it, they are just more prone to it and get it sooner.
