I purchased these chicks in April 20th of this year, and I forgot to ask the shopkeeper for their ages. It has been 44 days since I have purchased them, and now I would like to know how old these guys are. I already moved them to their coop+enclosed run that we have built. I'm pretty sure they are all hens. I should probably mention that this is my first time purchasing and raising chicks. Below are pictures of them in the brooder in April, and pictures of them today in June. Any ideas?
