So: my Serama is broody. She absolutely doesn't leave the nest unless we kick her off, and she certainly isn't laying. I only have one other small bird in this yard, and she's a bantam Cochin who is close to laying again after raising chicks- I saw her peck one son yesterday, so she's possibly the culprit. This is the egg, and again with 2 medium EE eggs and a pullet Serama egg- my daughter loves to blow them out: We automatically assumed it was a wind egg. Then Lydia went to blow it out, and look! There was a yolk! It must have been the size of Abe's noggin!!
