Your hatch rate is at 21% ,,,, which should be in reverse,,, non hatch value.
What do you suspect the problem was with the shipped eggs??? Infertile, or shaken in transport?
Same question for those from your hens.
the shipped eggs were fertile except for 1 of each batch. issues were bad air cells and my incubator lays the eggs down. I put them in cut up egg cartons and hand turned. I kept all non clear eggs in until 5 days late. Just in case.
My chicken eggs were fertility issues at first, on 16% layer.
Then One pen seemed to be having more late quitters than the other on 20% chick starter feed.
Broodies are breaking eggs and ruining the whole batch. Had this last year too.
Also the weather was not helping
The first 12 shipped all but 2 had bad air cells. The 2 made it to lockdown but never pipped.
I had 12 turkey and 4 of my eggs from one of my breeding pens being fed layer feed. I took the turkey eggs out at lockdown and gave them to 2 different hens.. 8/12 hatched. 2 of my chicken eggs were not fertile and the other 2 hatched. One chicken hatched may 3rd and the other 4 days late with the next shipped eggs.
The 2nd shipped eggs only 3 had good air cells and only 1 hatched. Another pipped and partially zipped. rest were early quitters
the next batch of incy eggs were out of 2 breeding pens, being fed chick feed .. lost power at beginning of lockdown for 3 hrs
Hatched may 31
pen b 8 set 6 fertile 3 hatched... put under broody hen
pen b skinny eggs I wanted to see if they would hatch.. stayed in incy
2 set 2 fert 1 hatched, but died at 5 days due to navels blow out... got my answer. don't set these eggs.
pen a 8 set 7 fertile 6 hatched .. stayed in incy during power outage.. after hatch put under a broody hen.. who was due at same time. Most of her eggs had egg on them,
put her eggs that looked ok in incy.. one hatched June 3rd, thinking this may have been an added egg..
June 6th took that chick and put under another broody hen who is my most successful broody who was in the most successful brooder box. .. who had 10 fertile eggs from a 3rd pen, none hatched .. 6 tried but didn't make it out. Remainder eggs were a mess and none look to be alive. Nasty nest. Supposed to hatch June 5th
now everyone is getting turkey feed, since there are poults in most pens. I will see how they hatch... just waiting on a broody.. although mama turkey seems to be going broody.. she may get chicks instead of poults.
