I have a silkie and a polish. The silkie went broody. And we introduced 2 babies to her. Now she is a great mum. The polish doesn't go broody. But she is so interested in the babies. She is always helping the silkie to take care the babies. Now, we have a 2 mums and 2 kids family. And the polish stops laying eggs. Is this normal? When the hens will lay eggs again?
