Not just crowded but sardine can cramped....and probably seriously nutrient deficient, depending on the protein percentages of mash and scratch and ratio of mix.I am feeding layer mash and scratch. Coop is an old pup trailer so 8 ft wide and I guess 10 foot tall and 20 foot long We did not have snow til Christmas day, so they were in the run every day. They are pecking at rear ends til bloody mess and, if I don't catch it early enough, dead. As I said I had to remove 13 of them and had 2 dead in the last 4 days. This has been an ongoing problem but is dramatically worse in the last week.
