Hi there! I've had chickens for 2 years (RIRs) but never had a hen go broody. Recently one of our favorite hens Mavis decided to get all broody on us, so we let her give it a go. One egg was fertilized and viable so we waited with eager anticipation. However, due to a crazy day, we didn't get out to check on day 21. On day 22 we went out and the chick had hatched but was dead. Do you think another hen killed it? I guess my main question is, what did we possibly do wrong? We have only had mail order pullets before, so we have no idea how much or how little to assist in this process? We gave her 6 more eggs to sit on yesterday, so any tips on what we can do (or not do) to have a more successful hatch would be greatly appreciated! Thanks!!
