I have 1 rooster, 7 laying hens, and only 2 adult guineas. (I had 9 originally, but when they free-range, or refuse to come into the coop at night, they have been picked off by predators.) I love guineas! So I ordered some keets that are roughly 4 weeks old. They live in a heated brooder. Just recently, I've allowed them loose in the fenced pen area outside of the coop during the day. The adults are all off hunting until evening. My question is: When they are old enough to survive without a heater (late October) and probably 50 degrees here in TX, how can I introduce them to the coop and the adult chickens and guineas? Right now, no adults (chickens or guineas) seem to have any interest in them.
