This info is from 1998, a bit outdated on the genetics front. Porter's site is current & updated regularly. I would trust it rather than this 1.Pics of Lilacs here: http://www.feathersite.com/Poultry/Turkeys/BRKLilac.html
Only 1 real difference between the 2 colors. Both require a double slate gene. Lavender is black with 2 slate genes. Lilac is bronze with 2 slate genes. Colorwise, lavender is the same pale blue color all over. Lilac is the pale blue with red tints on tail & wings.They do look pretty similar snood wise.. I'll get a pic of their feet together... if they will both sit still. :/ lilac, lavender.. sigh. I need to do some more reading! They are both a purple color so I thought it was the same! Haha.Looking too similar to tell at this point. Can you get legs side-by-side like you did snoods? At this point, looks like 2 the same gender, but can't tell which gender. It may be easier to tell in a week or 2. A male will be noticably bigger than a female. Oh, and the 1 you are calling lilac is lavender. Ralphie has the lilacs.
At this point, with prominent snoods & chunky legs, I'm guessing 2 toms. If there's a distinct difference in about 2 weeks, I may change my prediction. I'm about 75% sure it's 2 males.
