Feeding breeders: support fertility without overfeeding
Breeder nutrition aims to maintain condition and support viable eggs and chicks. More feed or more supplements does not automatically mean better fertility. Both inadequate intake and excess body condition can work against a breeding programme.
Start with a complete programme
Use a feed intended for the flock's breeding needs and follow its directions. Protein, energy, amino acids, vitamins and minerals all contribute. A breeder-labelled concentrate is not necessarily a complete feed: check whether it must be mixed with other ingredients at an exact ratio.
Track the male and hens
Observe mobility, mating, feather condition and access to feed. Record fertility estimates and hatch results by pen and date. A rooster that crows and looks impressive can still have fertility problems. Avoid making several management changes before the next test hatch.
Interpret results carefully
Clear candled eggs can include very early embryo deaths. Poor hatch results can reflect storage and incubation as well as breeder performance. Ask a poultry nutritionist or vet to assess persistent problems rather than adding minerals blindly.
Next step: keep breeding and hatch records together and review body condition routinely. The goal is strong birds and traceable results, not maximum weight.
