Sorry for the loss of your friend. That's always hard.Yes they are marked. With a pencil, but the pencil numbering is mostly rubbed off from her turning the eggs at this point. Today was the first that extras were with the original 4, so I wasn't too worried....
So, day 19 for me and I have 7 of 15 eggs pipping and two have begun to unzip. I can hear active peeping. It's so loud sometimes that the dog runs in to look and starts whining. I had to rush to the feed store to get chick starter and round up my heat lamp and bedding for the newbies. Both of my broodies have quit, so I don't have a hen to put them under as was my plan. The EE may still get on the nest, so I'll try her if at all possible, but it looks like these will be brooder raised, then moved outside when they've got enough feathers.
I didn't expect this much activity on day 19! I started the count at 0 on the first day, so today is definitely day 19. Stormy weather coming! I hope we don't lose power.
