I bought some chicks early this year, the only ones they said they hatched were Orps and Marans. I picked all the chicks without feathered legs they looked like Orps some were a week old, some a couple of days. I had 2 that died suddenly they were very thick, similar to Cornish, but had single combs. This is the sole survivor of the odd balls. I am not that familiar with Marans, but could it be a clean legged Marans? I am very familiar with Orps, since I raise them and it definitely isn't an Orp, maybe a ,mix?
