So I am not new to chickens but I resonantly moved to a farm and decided it was time to hatch my first brood. I have had 5 eggs hatch one on day 18, three on day 19, and one on day 20. I am now on day 25 and not a single pip since. Is it time to throw in my towel? I started the brood with 36 eggs but from what i can tell from candling only 17 fully developed.
