I am sorry to hear about all the problems you are having with your chicks. It does sound like a problem with genetics,food or water. Is this feed the same as the feed you are giving your older hens. It may have too much calcium if so.
I put my second round of chicks on lockdown Tuesday. These are being hatched in my home made incubator. The one made from the wine incubator. I will find out if the modifications made a difference. 12 eggs made it to lockdown. I have 4 pips so far this evening
. I should wake up to some little ones in the morning.
I have the next round of eggs ready to go after these. They will be silkie americauna mixes. I am anxious to see the results.
