About 3 months ago I got two Leghorn hybrids. They were supposed to be 7 months old and 1 year old. They live together with my 2 Baladi hens and eat the same layer food. I do not use artificial light in the coop, but the Baladi hens have already gotten over their winter break and are now laying about 3 light brown eggs a week per head, which is normal for them. Not so the Leghorns - I get about 2 biggish white eggs per week from them, not sure if it's one hen laying 2 eggs or each of them just 1 egg. Why? Could it be that they have a longer winter break? Or could it be that they are simply a lot older than the seller claimed and "spent"? Any other idea? They don't look ill.
