My in-laws were visiting and saw our cornish x. They had some last year and when they went to cook them they were very tough. My mother in law had to get creative in cooking them. I do not know what the birds ate, their breed or anything. But this has me a little worried because the person who raised their meat birds has experience. So I have 43 cornish x. They are 2 weeks old and just starting on the 12 hours on/12 hours off feed. I am feeding an organic feed for meat birds. They will be processed at 9 weeks. They are presently in a shed but moving to a tractor my husband is building in another week or so. Is there anything I can do at this point to prevent tough birds? Other tips? Thanks!
