Hello, I am new to this sight. I've actually been reading here for about a month and have learned an awful lot! Thank you all for so much info. I had Serama eggs setting(my first with my new incubator), and I got 5 out of 7 to hatch. There were more eggs but not fertile or quit developing, so I discarded them. I had read somewhere on here that they should hatch within 19 days(instead of the 21)because they are smaller. They actually hatched at day 21, five adorable little fuzzies hatched Xmas eve day. I've got two eggs left, developed with a good air sack. How long should I wait to dispose of them, 1 or 2 days, or possibly 3?? Thanks for any help.
