So i always get pretty decent responses here. I tried to hatch Marans eggs. Many went full term but did not externally pip. I waited and waited and did float test to see movement and saw none. I opened up the eggs and most if not all had internally pipped and then died. There did seem to be alot of fluid by the chicks head so possible drowning? The air cell looked adequate. I ran humidity lower than normal as suggested. 35-45 during first 18 days. Also i usually put my eggs in egg cartons for lockdown and have pretty decent success with this method in the past. I would like to try again because I really want to raise Marans but I don't want to incubate until I have a better idea of what went wrong. 1 chick did survive but i assisted. The chick is weak and has deformed feet which i am attempting to mend before making the decision to cull or not. Any help or advice would be greatly appreciated especially if you have experience with Marans.
