Hello, these are my first chickens, they look like those featured in the guidelines thread X) i bought them last week from a pet shop, still i am wondering about gender and breed ? yellow one is 45g black one is 55g they ve just started plucking down feathers i m guessing they re in their second week ? more pictures coming. also wondering if something's wrong with them :/ their head is diving when they sleep and and everytime i hear crackling sounds from the beak or nostrils. occasionally they have bubbles in the nostrils. then i encourage them to drink. the black one was drooling the other day. it has some slight yellow dirt on one side of the beak and nostril. the vet said it was fine cos she s very energetic and eating well ? what do you think ?
