English to Spanish Science Livestock / Animal Husbandry field study - vaccines

For the in ovo route, approximately 70000 embryos were vaccinated in total from the two farms.
Following in ovo vaccination at each site, the eggs were placed in clearly marked hatcher baskets before being placed in hatcher units.

All test vaccinated birds that received the SQ vaccination were transported to the cooperator farm and placed in clearly identified houses.
Approximately 70,627 viable birds hatched from the in ovo vaccinated eggs and were transported to the cooperator’s farms and placed in clearly identified houses.
Extra birds that hatched from the embryos that received the test vaccine were placed into overflow houses, and were not a part of this study.

are they "cestas incubadoras"/"unidades de incubación" ?

thank you all!
