Love these birds first time chicken keeper. Not sure if I have hens or roosters though. They do not have the spike yet. One I thought was a Rooster seems to be a Hen as his crown is not a bright red. Largest of the bunch and keeps an eye on the others. Might be a transgender chicken. Seems some Hens start to take on the characteristics of Roosters from research I have done. Anyway when do they grow this spike on the foot as I found out was a sure way to tell a Hen from a Rooster? I got mine around Easter from the local farm supply store. Been pondering this new hobby for several years now and am in it full throttle. Love the birds pick them up and play with them regularly. Some are sweet some are aggressive. Have 6 in all was told all were Ameraucana's 3 buff and 3 are the russett color. But when do they get the spike on the foot? Thank you for any info anybody can relay to me as I am a total newbe into this amazing creature.
