Ive heard people say not to breed brother to sister for genetic reasons but others say theyve done it with no problem. What are your thoughts on this? Please explain it so its easy to understand, im clueless about genetics haha.

Brother sister matings should only be utilized when:

1. Setting a strain.
2. No other birds can be found.
3. The original parent birds were excellent.

Brother sister matings are very useful; however, you have to know what you are doing, what you are looking for and what you've started with. These are very important consideration.

Do you mind sharing what you are working with and why you are considering this type of mating? Also, how long you've been breeding chickens?

I only breed for fun. The only fertile eggs I have right now are from brothers and sisters and I want babies so im tempted to hatch. They are seramas from a pair of pumpkins, so if I bred brothers and sisters would that produce more pumpkins or not?

Pumpkin is a weird color, but the answer is 'yes.'

Breeding brother sister once is no problem whatsoever. If the parents were brother sister then hatch rate might be a bit off but that is about all. You might see some crooked toes/beaks but might not at all. Go for it.

You can usually safely inbreed chickens for 4-5 generations before they start having any real inbreeding problems, but I would personally recommend infusing some new blood into the flock with the 3rd generation.
