I've hatched chicks...but this is the first duck ...my friend gave me 2 ducklings and lo an' behold breeding pair! so decided to try hatching...out of 6 ...4 are viable here are photos at day 14....my question is when should I put them in the hatcher? I know on average they say 25 days. I know that chicks go into lockdown on day 18 and hatch day 21 so I was planning to put the pekins in the hatcher at day 21 but need (would like some advice). I want them to hatch successfully so if anyone has info I would be so appreciative!! thank you! I think these are day 7-10 sorry about the confusion. video was just taken right now...all 4 eggs moving like this one.
