Our TSC had them and so did LC, and they were the last ones left.. which means they may not order as many this year... who knows... LOL and as far as a BLRW/Leghorn mix goes, probably a great dual purpose mix, but the eggs would be very very off white (or eggshell!!! ROFL!)
You know what's funny? The leghorn was a chick I got free from some college students at UT who didn't realize the needs chicks had and gave them too me, it was all pullets! 2 were Buff Orps, which I sold and the Leghorn! What luck!
put an old english game cock over your white leghorn (will be called an egg laying white, bred all the time to put some sturdiness mentally and physically, back into the breed), and the hens will be egg machines still, and good foragers and calmer to you, but more chicken aggressive, fly great, and need combs dubbed (which on them will be easy, as ive had them just get ripped off in fences). mate a cockeral from the babies back to original hen, then they will be more nerotic to your liking.. lol though the cocks will be very loud and crow a lot, but decent sentinals and fenders off of preds (even at night, if you keep very low watt bulb in their area). i had the mixes i mentioned and over all were great, but the hen thought she was people and came up to the door and window tapping on and clucking, waking me in early morn for lubbinz and treats, and wasnt great about were she laid, but made nest sort of and made such a fuss about it, you knew! the one rooster was a newsance, aside from best at sentenal duty and would go crazily after hawks, owels, cats, dogs, people he didnt know, if they scared the hens. oh, they will tear your yard totally apart, aside from areas you teach not to go in.
