I have a moma hen on 12 eggs - I thought they should of hatched 3 days ago. So I did the light thing on 5 of them dark with an air pocket was all I could see, on the 5 egg I drop it there was a live chick - but not a 21 day old, it was small & the yoke was still pretty large.... She has been a great moma sitting non stop. BUT today she when out in the yard & is still out there 15 min now & seems to be acting odd like in a panic and scratching & eating like crazy ( food and water right next to her nest & treats ).. I checked on the eggs and they are warm.. Do they stock up before the hatch, get there last outside outting before they hatch? It is 55 out side I do have a heat light on in the coop.. Whats to long for her to be of them? Now I dont know what to do I am running around like her in a panic.. Do I bring the eggs in and hatch them? Candel them again.. None are pip.
