Hello all. I have 3 black australorps who are 21 weeks old and not laying yet. Their combs are definitely red, but they're not really squatting or acting more docile yet. We're not feeding layer feed. I thought you were supposed to wait until they started to lay because they didn't need the extra protein. But now I just read somewhere else that you are supposed to be feeding them layer feed once they are 19 weeks. Should I start now? Also, they don't free-range much. Most days they get out for an hour or so, but not every day, so the likelihood that they are laying somewhere else is pretty slim.
