Needing a little help with my speckled Sussex

[Cedar grove]

I have 2 speckled Sussex birds around 3-4 months of age. I was told they are both hens one definitely is but this one I'm not sure about.... It's tail is different from the hen. Any guesses male or female? I just discovered that 4 of my wyondette hens are Roos

The top pic is my female the bottom 2 are the bird in question

Here is a grainy pic of the bird in question (don't mind the goat photo bombing the chicken )

From what I've seen and experienced from my little flock and the comments of wisdom from others. I would side on he/she being a pulley at this age. 3 to 4 months would bmmeen the comb and wattle would be more pronounced and red than what you have. Also the tail feathers are very short and round from what I see which points to a pullet. I have a 3 month old Delaware in question pictured below to show comb wattle developement that points to a cockwrel

They are very nice looking birds! I used to have 2 speckled sussex roosters! Your lucky, they both look like hens in my opinion!

Your SS is a pullet. I have one roughly the same age
