Newly hatched chick! Breed help

[loulusea]

Hi! I have a flock of chickens and I am incubating my eggs for the first time. I have one rooster and a variety of hens. Unfortunately I do not know which hen laid the specific egg of the chick that just hatched. Hoping someone would like to play a guessing game for fun with me bc I would like help trying to identify the potential breed(s) of this chick.

Here’s is what I know:

• The father is my BCM rooster (I got him from a breeder. He’s very close to SOP)
• The egg shell is a light brownish peach with small brown speckles splashed over it. (See photo of shell).
• The baby chick is black and white and has feathered feet (feathered feet genes probably come from dad bc the only other feathered footed girls I have is a Buff Brahma and a silkie- and this egg did not come from either of those gi. Slate-ish legs. Black beak. (See photo of chick).

I can identify which hens laid some of these eggs, but I haven’t figured out which one laid this egg. Here’s a list of possible suspects/hens for us to guess from:

1. Sapphire Gems
2. RIRxBuff Brahma crosses (one of these has feathered feet)
3. RIRs

If you’ve made this far, thank you!!
