Hi there, a few weeks ago a well-intentioned family member popped some abandoned partridge eggs underneath the chickens we own in the hope that the hens would sit on the eggs and raise them as their own. They’ve sat on the eggs happily until now, but have started to attack the chicks as they’ve hatched. Despite our best efforts, they don’t seem to be drinking or eating too regularly, despite them needing the most food and water at this stage. We’ve moved all of the eggs underneath a heat lamp, placed starter chick crumbs in a small container, placed water in a small container with some pebbles in it, and a fluffy toy for them to huddle in. Attached are some photos, is there any advice or critical things we should / should not be doing? We are all admittedly very inexperienced, and are working off of internet advice and our best intentions. Thank you very much, and I look forward to reading your answers!
