I wouldn't be concerned yet. Wattles (not waddles) don't look horribly big right now. I *think* wyandottes tend to mature early. My first birds were SLW so I do know the struggles.
If I am not mistaken, it's a cookoo maran. (Pink legs) Depending on age, looks like a cockerel to me. He looks fairly young, as in maybe 3 months tops. (10-12 weeks if that.)
I'm by no means an expert, I have never ordered from IDEAL, but looks like a black australorp cockerel to my very untrained eye. Like I said, just a guess.
White chickens are very hard to photograph to be able to see 'rooster' type feathers. I'm guessing it is a he since he is mounting the girls. I have ten hens and they have been laying for exactly a year now and I've NEVER gotten 10 eggs on any day. 3 eggs a day is awesome!
Is he not crowing?
Good luck with the move!!! I know of someone else who made that exact same move a year ago!! I love Montana and would LOVE LOVE LOVE to live in Kalispell or nearby!
