Been lurking a long time and just tried hatching with many difficulties. Incubator made it to day18 and the 4 eggs quit. Second attempt lost power 2X but was luckily able to put some under a hen that went broody the day B4. Her 1st try-a 13 mo. Splash silkie. Everything went well. 1st hatched day 21 and 2 were pipped. Next hatches day 22 and is found dead that afternoon. I thought it a fluke accident b/c I tried to shut her in coop but she got out and I thought she couldn't get back so new chick got cold till I noticed a few hours later. Next day egg 3 seemed to be struggling and thought egg might've gotten too cold too. Finally assisted with great results but next morning found dead too. Mom was with chick #1 in another corner not on nest- this one too seemed to have been alone too long also. The 4th egg I put back in the bator since she left the nest. It just hatched but today I found chick # 1 dead in nest and do not know what to do, why this is happening. I thought he was stronger and would be just fine. Is my hen a bad momma that is stepping on them, is the other hen the killer? Do I dare give her the other last chick- She is still broody sitting on eggs again? Did they get to cold, were they hurt by a hen, or sick. The rooster is gone, so no more fertile eggs.
