I have an Old English Bantam who always sits on eggs from my large hens. i take them away before they develope but i was wondering if i could let her sit on them and let them hatch. she sits on 5 or 6 each time and to keep them all warm she has to put her wings out. would they hatch if i let her sit on them and if they did would they be too big for her to care for. thanks for any help
