My children named their chickens.
7 yr old named hers Gummybear ( BCM )
10 yr old name his Shadow ( Barred Rock )
2 yr old named his Buk-buk (Columbian Rock )
6 yr old named his Joey (Columbian Rock )
All Pullets.
I read/hear a lot of stories on here about owners getting rid of they're chicks online to find out that people voted 9/10 Cockrel but in fact it was a pullet. Always best to wait it out. I myself go crazy trying to play the guessing game. Time will tell.
Also looks like a pullet in my opinion...
Dirt in a raised coop? Never heard of anyone doing that before although it would make it so much easier to compost and use for plants/gardening without having to wait a lengthy time for shavings/straw to break down into compost.
