My 25 week old BO hens have been laying for about 2 weeks. Changed over to layer feed with 20% protein. Is this the right amount of protein? So far the eggs have been awesome, only problem I also have 4 muscovys.Can they eat the same feed a the chickens, or should I get them something else? Will it hurt them to eat this feed too. It would be a problem trying to feed the separetly,they all live together and share the same feeders..
