I'm on day 19 of waiting on my Silver-laced Wyandottes to hatch a when I checked on them this morning, the temp said 77 and my heating element went out. I'm not sure how long it was like that but I ran to the store and got it fixed. I'm just curious if the chicks won't hatch now? Or will they be alright? I've never hatched eggs before. Thanks in advance for the help.
