We have thought about them being too big. I believe they are CornishX. They don't look too big to us but maybe it is because we had turkeys in the past. Thanks for the comments.
We bought two dozen meat chickens this year and all was well until we put the birds outside at about 5 weeks. A few birds at a time are dying off and it looks like we are going to lose them all eventually. It starts with the chicken appearing to get lame and their legs become completely stiff...
