At $50 per Cream Legbar chick from MPC, as soon as I saw one was an "accidental" cockerel I named Strawberry, I decided to breed him to the pullets to get some free $50 chicks.
From that first mating, I got a feisty pullet I named Ladybug. This past spring, I bred her to her daddy Strawberry, and I got a pullet I named Trixie and a cockerel named Toots.
I consider Toots a "spare roo". He won't be breeding. By the way, so far he and his daddy are getting along very well in spite of Toots experimenting with the hens under his beak. And all these Legbar offspring seem healthy and normal.
I also have a mix from Strawberry and an EE. Blue eggs are hard to tell apart, but Betsy is a keeper anyway.
