She did abandon them. I’ve had many broodies, it’s not my first time. She was unhappy the two weeks she had them, always wanted out, not letting them under her so I had to put a heat pad in brooder. One nearly died it was so cold. On many occasions they had to be locked in their kennel as she’d just stand ignoring them. A good broody should respond to their chicks cheeping, especially when it’s 8c outside. They’re not living with the main flock, they’re staying as they’re own bantam flock, so no need for reintroduction. Thanks for the tips on that though.
Poor kiddos. I've had a couple bad moms too, and their chicks get taken by CPS (chick protection service). Every once in a while you get one that's great at the setting part and there's just something wrong with their chick rearing instincts. Sigh. I'm glad they're safe and well on their way!
